Hello!
Two for each text within one body paragraph is definitely enough, although if you could integrate a few more good quotes, that is always a bonus

However, since you’re only planning to do two body paragraphs, I’m assuming your paragraphs are going to be rather long. If you only have four quotes per paragraph, it might seem a bit lacking in quotes.,So in that case, maybe aim for at least three per text?
This might be a bit irrelevant but I’m just wondering whether having four paragraphs in total is a good idea? Because comparative text response explores two texts, there’s quite a bit to write about. That means your two body paragraphs might be quite long and might be at risk of having a mix of ideas which could get a bit messy. Also, I think having more body paragraphs might make it easier to clearly show your ideas/arguments. Nevertheless, this is just my opinion - if you tried out your structure and it works, go for it.
