Time to pot these?

I’m trying to bring this beauty back to life, first pic is how it started, next few pics are how it’s going. It started to lose almost all its leaves, so I cut some branches and put them in water. A month later the bare stems started to sprout new leaves! And the ones in the water did too! The roots are about ideal length to pot (I think) I’m just a little nervous on how to do it. I don’t want them dying, they seem to be thriving in the water lol. Any tips on potting these would be appreciated! And also what to do with the old tree that has sprouted new leaves. They were growing like crazy and then stopped, I don’t know wat to do next lol. Thank y’all in advance!
