The leaves look like some kind of legume plant. From googling plants online, I think it may be Melilotus albus or white flowered sweet clover. If so, it sounds like it's pretty invasive. I don't know where it came from unless it was in the potting soil. I hope the small plant is foetida. The seeds were a few years old so I didn't know if they would still germinate.

Possibly Echeveria pulvinata or Echeveria harmsii

This plant has tendency to grow leggy, and with not enough light - even more. The soil mix is already mentioned as not very good either. Prune off the branches, let callus as Tiffany suggested. I wouldn't recommend to root them in water; they are better off to pot up. These cutting were left sitting without any soil for about a week. All were potted up in well-draining mix and spent summer outdoors: Same cuttings (indoors in winter, under lights):

I was thinking that probably some greedy poor natives are digging up those beautiful plants and selling them on ebay. Just like the same kind of people that are collecting every last native ginseng plant in the south over here. Just like feathers in British hats nearly wiped out the most gorgeous birds in the world. It's such a shame that so many blind people have no reverence for nature at all. I'm sure Sudan would agree with me. He was the last living African male Northern White Rhino in the world. And he died in May. All attempts to bring back the species have failed. They are probably gone forever. While rich Chinese gloat to their friends about their rare horn potion that they use for an erection. ( myth) They will reap what they sow.https://youtu.be/ALPwujKU4bs
