For #3, you can count the number of rooms in your house, and the apartment outside, every room will have a woman in the end.
As for #2, they way it's made, they can add a lot of locations. I would suggest every woman has a location, some locations are in the same section, so it's most likely that it cannot be more than the number of empty rooms (added the one or two woman who's story doesn't exist yet). Having said that, the police woman, had 2 locations in different sections (So that theory is not exact).
As for #1, every woman has her story, and then we get a few small games to fight the main villian (This is based on Town of Passion and the first Zombie Retreat). The first Zombie Retreat didn't have a hall of games like Town of Passion, so I don't expect one either.
So in other words: No idea...
