I am thinking of doing this to these films:
- Delta 100 exposed at 50, overdeveloped +1
- Portra 160 exposed at 50, overdeveloped +1
- Ektar 100 exposed at 50, overdeveloped +1
What kind of look can I expect from the final result?

I don't think I understand... Pushing film means you will underexpose and then adjust during development. What you're saying is you will overexpose film yet push at the same time, which contradicts each other

Ah that makes more sense! If you overexpose you'll end up with denser negatives when developed regularly, and overdeveloping will only make this worse. I have not done this myself before, but I am not sure if you would want to do this

If you are setting your meter to ISO 50 while using ISO 100 film and following its recommendations, you're overexposing the film by one stop. If you are then overdeveloping by one stop, your developed negatives will be approximately two stops denser (darker) than nominal. When you scan such negatives and reverse them to positives, the resulting images will look washed out with no dark shadows (unless the scene you shot had a very wide dynamic range).
I understand overexposing reduces contrast and I am pushing to counter that.
Overexposing by one stop and then pulling development by one stop will reduce contrast compared to exposing and developing nominally. This works well for very high contrast scenes. If the original scene was not high contrast, the result will look dead and lifeless. Increasing development of such an overexposed film will just make the dull, lifeless result grainier and have even less highlight detail. Once reversed many areas will be an unrecoverably uniform "paper white" with no detail in them.

What happens if you overexpose and over develop (push exposure with push development)?
You would get a film that appears doubly "overcooked". Negatives would be dark and dense. Slides would be light and thin. Michael C and Kahovius describe the appearance in more detail.
However, Hueco points out that some films, such as Portra, tolerate overexposure with normal processing very well.
The Online Darkroom: How to read a negative shows this example:
Don't do it unless you are compensating for long expired film.
Push up, pull down.
What happens when you push or pull depends on what you're pushing or pulling. Use of the terms with respect to development is fairly common and understood by most people. Use with respect to other aspects of photography can be confusing.
Push development = over development, usually to compensate for underexposure. The expected result is increased contrast and grain.
Pull development = under development, usually to compensate for overexposure. The expected result is decreased contrast and grain.
Push exposure = over exposure. Compensate with "pull development".
Pull exposure = under exposure. Compensate with "push development".
Push/Pull ISO. On digital, this is analogous to push/pull development. On film, it's ambiguous. It could refer to push/pull development (where the effective ISO of the film is manipulated) or to changing the ISO dial on the camera, which has the opposite effect. Probably best to avoid this usage.
As with the exposure triangle, pushing or pulling during exposure is compensated with a complementary action during development to maintain "proper" appearance of the negative.
To add to the confusion, people often speak of pushing or pulling film without specifying exactly what they are pushing or pulling. In these cases, they are typically referring to the action in terms of development along with the compensatory action for exposure. For instance, by "push" they mean that both push development and pull exposure will be performed.
When dropping film off at a lab, it's safest to tell them specifically what ISO you shot at. Then let them adjust development appropriately. If you don't tell them anything, they will assume "box speed", the ISO as labeled on the cassette.

Maybe it's regional differences, but I was taught it this way back in the dark ages: "If you pull exposure (underexpose) you then push process the film (over develop). If you push exposure (overexpose) you then pull process the film (under develop)."
– Michael C
May 28 at 13:55
The point is, my instructors called shooting ASA 100 film at ASA 200 "pulling exposure", not "pushing ISO (or ASA)" or "pushing the film". This made it clear that if you push in exposure you would compensate by pulling in development, and vice versa.

A dense, contrasty negative with blocked-out highlights and more grain than you'd normally expect from the film.
I'd be curious to hear why you want to do this and what your workflow will be after the films are developed – conventional silver prints or scans perhaps? The usefulness of the negative is determined by what you want to do with it afterwards.
According to Evaluating your negatives:
An overexposed negative that is overdeveloped appears extremely dense and sooty and is laughing referred to as "bulletproof". The grain will be very excessive for the film used and the highlights will be unprintable. There is almost no way to make full scale prints from such a negative.
Just scans. I understand overexposing reduces contrast and I am pushing to counter that.

@Berry Overexposing film does not reduce contrast. That is plain wrong.

@Berry Again, pushing is the combination of exposure and development. If you're overexposing, that's not pushing.

As has been stated, in most cases, this is a bad idea. However, if you plan to cross process C-41 films to E-6, then what you’ve listed is a starting point.
Normally exposed C-41, when crossed, comes out thin and lacking contrast. Starting with one stop overexposure and one stop overdeveloped is a good starting point. Though, you may end up at +2 stops overexposure,+2 stops overdevelopment with certain films (lookin’ at you, Portra).
A bit more on your examples:
Delta 100 exposed at 50, overdeveloped +1 - You'll get dark, dense negatives. Highlights will probably be blocked. This is just a bad idea in general.
Portra 160 exposed at 50, overdeveloped +1 & Ektar 100 exposed at 50, overdeveloped +1 - as these are both color negative film, we can treat them similarly. The overexposure at 1 stop won't actually cause any problem at all. Both of these films easily tolerate that. (Ektar proof: https://www.youtube.com/watch?v=jp4eJvTBjKU | Portra proof: https://petapixel.com/2018/02/05/test-reveals-exposure-limits-kodak-portra-400-film/) However, the overdevelopment will darken the image overall and increase contrast. That combined with the overexposure may compound the issue. In general, feel free to overexpose your color-neg film by a stop but please, develop normally for best results.

You will blow out (make white) the highlights significantly. The colors will be difficult, if not impossible, to print correctly at automated labs.
Typical SUC (Single Use Cameras) back in the day had ISO 400 or ISO 800 film, and exposed it as if it were ISO 100. That way when they were used indoors in bad lighting the lab had a chance of printing them.
The cost of 'pushing' film (at least in my lab) used to be about a dollar, and we did it by turning off the motor drive for 30 seconds (I think). So it could be the only roll in the tanks.
I don't think you'll like the results. If you're looking for that glowing, highlighted look that you see sometimes in prints it was more commonly done with slide film and a slightly blurred, over exposed duplicate shot stacked underneath it.

The point is, my instructors called shooting ASA 100 film at ASA 200 "pulling exposure", not "pushing ISO (or ASA)" or "pushing the film". This made it clear that if you push in exposure you would compensate by pulling in development, and vice versa.

That was almost 40 years ago. I don't remember the textbooks. LOL.

A dense, contrasty negative with blocked-out highlights and more grain than you'd normally expect from the film.
I'd be curious to hear why you want to do this and what your workflow will be after the films are developed – conventional silver prints or scans perhaps? The usefulness of the negative is determined by what you want to do with it afterwards.
According to Evaluating your negatives:
An overexposed negative that is overdeveloped appears extremely dense and sooty and is laughing referred to as "bulletproof". The grain will be very excessive for the film used and the highlights will be unprintable. There is almost no way to make full scale prints from such a negative.
Just scans. I understand overexposing reduces contrast and I am pushing to counter that.

@Berry Overexposing film does not reduce contrast. That is plain wrong.

@Berry Again, pushing is the combination of exposure and development. If you're overexposing, that's not pushing.

As has been stated, in most cases, this is a bad idea. However, if you plan to cross process C-41 films to E-6, then what you’ve listed is a starting point.
Normally exposed C-41, when crossed, comes out thin and lacking contrast. Starting with one stop overexposure and one stop overdeveloped is a good starting point. Though, you may end up at +2 stops overexposure,+2 stops overdevelopment with certain films (lookin’ at you, Portra).
A bit more on your examples:
Delta 100 exposed at 50, overdeveloped +1 - You'll get dark, dense negatives. Highlights will probably be blocked. This is just a bad idea in general.
Portra 160 exposed at 50, overdeveloped +1 & Ektar 100 exposed at 50, overdeveloped +1 - as these are both color negative film, we can treat them similarly. The overexposure at 1 stop won't actually cause any problem at all. Both of these films easily tolerate that. (Ektar proof: https://www.youtube.com/watch?v=jp4eJvTBjKU | Portra proof: https://petapixel.com/2018/02/05/test-reveals-exposure-limits-kodak-portra-400-film/) However, the overdevelopment will darken the image overall and increase contrast. That combined with the overexposure may compound the issue. In general, feel free to overexpose your color-neg film by a stop but please, develop normally for best results.

You will blow out (make white) the highlights significantly. The colors will be difficult, if not impossible, to print correctly at automated labs.
Typical SUC (Single Use Cameras) back in the day had ISO 400 or ISO 800 film, and exposed it as if it were ISO 100. That way when they were used indoors in bad lighting the lab had a chance of printing them.
The cost of 'pushing' film (at least in my lab) used to be about a dollar, and we did it by turning off the motor drive for 30 seconds (I think). So it could be the only roll in the tanks.
I don't think you'll like the results. If you're looking for that glowing, highlighted look that you see sometimes in prints it was more commonly done with slide film and a slightly blurred, over exposed duplicate shot stacked underneath it.

I don't think I understand... Pushing film means you will underexpose and then adjust during development. What you're saying is you will overexpose film yet push at the same time, which contradicts each other

@timvrhn I want to overexpose and overdevelop the film, but I want to know what to expect.
– Berry
May 28 at 12:35
Ah that makes more sense! If you overexpose you'll end up with denser negatives when developed regularly, and overdeveloping will only make this worse. I have not done this myself before, but I am not sure if you would want to do this
