in/at the same place,have (already) stopped

Which sentence is correct or both are acceptable?:
1.we live in the same place
2.we live at the same place
3.I have stopped already growing up.
4.I have already stopped growing up.

Thanks a lot.

“We live at/in the same place.” – Both are possible, but “at” probably means the same building, while “in” could just mean the same locality.

“I have stopped already growing up.” – No.

“I have already stopped growing up.” – Possible, but a rather unusual thing to say. (You’re aware of the difference between “growing up” and “growing”?)
