I still think it's the first pot, and I still think it's 'String of Hearts' Ceropegia Woodii. I think one of the two plants is regular, and the other is a varigated 'String of Hearts' Ceropegia Woodii. I also think both the plant at the front of the room, and the one at the back are 'String of Hearts' Ceropegia Woodii. I just can't tell if the pot in the back also has two different plants in it, a variegated and regular.
