My mom’s aunt and two female cousins live together and I’m not sure how to address their invites. The Misses _____? Both the daughters are unmarried, though I believe one of them is divorced, I think she kept her maiden name.
ALSO, We have a couple of guests who are married, both Doctors an the wife kept her maiden name. Do I say Drs. HerName & HisName?

For the doctors, what you wrote is fine.
For the relatives, I’d probably write out each of their names, but I don’t know what the convention is for that situation.

I think it should be as follows
Dr. John Smith and Dr. Jane Jones
Dr. Smith and Dr. Jones
As far as the related females that live together, technically if they’re all adults they should each receive their own invitation.

All three that live together need their own invitations.

For a pair of twins that live with the parents (only the twins are invited) I wrote “The Misses Oldest and Youngest Twin”. They’ll be seated at the same table as they are in the same circle of friends and they would not be insulted by combining invites (this is the first wedding in that circle so proper invites wasn’t even expefcted).
