As for the maximum of 4 buffs, only buffs/skills that appear in the top left of the screen are counted. These are skills affecting the stage and usually carry over to the next round. If you add a 5th skill, then the 1st one will be removed. Circe's skill is a monster skill the skill icon appears on her own portrait (and not in the top left corner) and doesn't count against above skills.

You can indeed only have one combination active, that's a limitation set by Madhead. Besides combination, you also have combine skills and team skills. A combine skill gives two cards an additional active skill, but if used, CDs of both cards will be reset. A team skill is a passive skill when a combination of cards are in your team (like the 25 seconds rune moving time when you've Yog-Sothoth as leader and ally). But these combine/team skills are not really hidden as their info is available on the card itself.

You actually can have identical team skills in the team, if you have two Mother Nature Cybele, Divine Tree in the team with a ★6 Druids of Nature, then both Cybele's will turn into the Druids of Nature card's attribute. But perhaps you mean something else?
