Hi & welcome!
I would cut off the brown part at the tip and stick these stems back into fresh soil all the way to the bottom. Remove a few of the lowest leaves if you need to (don't bury any leaves.) You could do them as-is, or remove the top half (halves) and stick them in soil also to have more plants that are more compact. I don't know whether you prefer tall and skinny, or more of a rounded shape.
