2 Questions about user roles

We have a collection of both S2 pro and free sites. (latest versions)

We want a user to be able to login as Editor (or equivalent capabilities) so they can create and edit pages And posts on the sites, edit categories etc. which would require access to the admin panel (or parts of it anyway) to access everything.
We can not give them admin access.

Can’t see a way to do that. Am I missing something?
(note: our plugin guy is remote an unavailable - he’s in Ukraine)
