The plant I am referring to is the thin dangling plant. It seems to be growing well, but I have no idea what it is.
It is Sedum rupestre 'Angelina'. In lower light conditions it will be more green than yellow. In very intense sunlight it will even have some orange and even a touch of red. It is very etiolated/stretched out due to not enough sunlight. The leaves of 'Angelina' will curve backwards if there is lots of space between the leaf sets. It is a very hardy sedum. You could plant it outside if you have the space. Just break off a 3" pieces and insert the broken end into the ground. It will root very fast. I have found that it is somewhat sensitive to too much winter rain. Looking a little rough by the time summer arrives, but it can always be cut back. It fills in quite nicely.
The picture is an Angelina in my yard. It has lost some leaves for winter. The piece in the very back is shaded out by the rest. It is etiolated like yours, just not as much. The leaves have also started to bend backwards due the space between the leaf sets. Not as bad as yours because it is outdoors.
