how tho change number of posts in loop from specific categories

I anm trying to get my home loop query filled like this:

1. From all posts within all categories: show (just) 1 (most recent) post.
2. From some specific caegories: show 3 (most recent) posts (max).
3. Sort on publish date.

The combination 1,3 and 2,3 is pretty standard, but I can’t figure out how to script the two combined.

Appriciate to get some help!
