Let’s say I’m from instance A and use a community from instance B. Let’s say another user of instance C, that’s not federated with A but is with B, post in B. Can I see that post?

If the URL actually shows the address of the federated instance, yes - you’ll see the content. In that case you will not be signed in though.
If you visit the federated instance through your home instance, the content will not be visible and you’ll be signed in.
