I tried to keep it spoiler free on the first comment. 

4 females you can get to move in are all from the Jessica's  quest when you 'help' to convince them to sell. All are missable depending on your choices during the quest and later interactions.

I am not sure if this is all but I have 4 people in west wing, 5 in east human wing and 2 in east fey wing.

Some upgrades are definitely skippable for act 3. But there are a few missable women encounters around properties so I would encourage you to explore.
