The set is designed to be very flexible, so its hard to list off every possible setting, especially if you are creative with the tiles. Still, I'd say that the tilesets cover the basics for:
General nature tiles: park, forest, mountains, river, swamp, beach, etc
Town exterior: town, city, suburbs, farm, church, beach, docks
Interior areas: houses (living room, dining room, kitchen, bathroom, bedrooms, etc-- ), stores (grocery/general store, clothing store, vending machines), offices, fast-food place/diner, casino, cinema, school, church, tech labs, hospital/doctor
Dungeon: caves, mines, temples, sewers, science lab
I hope that helps.
Sorry for the delayed response, I'm not good at keeping up with the comments XD
