Show only certain posts on the homepage

I want posts to show on the homepage but not all of the posts, however I added some categories to my menu and I want the posts I take off the homepage to show on those pages – I’m basically saying I can’t just “make it private” or it won’t show anywhere else on the website either.

So how can I make a post not show on the homepage, while still showing other posts and keeping the removed posts visible elsewhere?

Thanks in advance for any help.
