If you mean stone by block, then the answer is yes, even though it might be a bit fiddly.
No reinforcement is needed when you are plastering. Regarding the choice of plaster, my old manual says that you should first apply a cement-rich mortar and then finish with a lime-cement mortar.

Thank you,
I have found a crack that goes through the entire foundation, from top to bottom, around 2.5 meters high and approximately 3mm to 10mm thick, it is continuous so you can see through it. What should I use to fix this? It has to be something that can be inserted into the crack, the question is how.

It sounds like a settlement damage, i.e., a part of the wall has a poor foundation. You should address this first. Repairing the crack will not help.
Yes, it is a settlement damage, a corner of the house that I need to fix. Many years ago, they dug in new water and sewer lines and they chipped away the footing under 1 meter of the corner and just left it like that. So I would need to stabilize and cast something there. I'm considering building a mold with rebar that extends around the entire corner, maybe 2 meters in each direction. Then try to cast in stages from below. I have to be careful so that the weight of the new footing doesn't load unevenly in any way.
Without having the full picture clear (i.e., how the house is generally constructed), it is difficult to give anything other than general advice. In most cases, it is probably best to first reinforce the foundation and then assess if any part may need to be lifted. Smaller settlements that have stabilized can be tolerated, but when the differences in height can be measured in decimeters, measures are required.
Hello, grateful for your answers!
The height difference in this corner is about 15mm, and it has been like that for many years. So it has settled and stabilized. So I'm not too worried, but to be on the safe side, I have a project to fix this corner.

Casting now at the bad corner. The old foundation on the outside of the wall, 10cm wide, is widened to a total of 30cm, and 18cm deep. Also casting a bit under the old foundation where it has collapsed. Adding reinforcement as well, on both sides of the corner, and long bent iron going 150cm around the corner on both sides, 4 pcs.
Casting with coarse concrete, using a concrete vibrator and seeing how the concrete moves under the old foundation.
Looks good
This is the first step, I will probably underpin the foundation step by step a bit further down. Then I will try to do the same thing from the inside, and connect the reinforcement so that at certain points it is intact from inside to outside, etc.
I will be occupied for a while
