My top choices for you:
1. Burmese star. Outdoors with a heated night box during warmer weather, indoors in a large closed chamber the rest of the year. Does not brumate.
2, Pancake tortoise. Outdoors with a heated night box during warmer weather, indoors in a large closed chamber the rest of the year. Does not brumate.
3. Hermanni. Outdoors with a heated night box during warmer weather, indoors in a large closed chamber the rest of the year, and you can brumate over the winter months.
4. Russian. Outdoors with a heated night box during warmer weather, indoors in a large closed chamber the rest of the year, and you can brumate over the winter months.
5. Box turtle. Outdoors with a heated night box during warmer weather, indoors in a large closed chamber the rest of the year, and you can brumate over the winter months. I don't know what the legalities are for your state on these.
6. I think marginated tortoises are too big for you indoor situation.
Groups can sometimes work, but sometimes they don't and have to be separated. That seems like it would be difficult with your limited space, so keeping a single tortoise seems better for your living quarters.
