When to transfer cuttings to soil?

Hello, this is actually a repot update since I've already posted here before beheading my violet ( and got many many advice form ya'll tysm), that was about a month ago so this is the result! I have a bunch of baby violets growing roots and small babies in water so im wondering when is the right time to pot them up? Do I wait for more roots or leaves to form? Also, when should I start acclimating the main plant (and the small ones that are in soil) to the regular room humidity? I've seen some roots since she's in a clear pot and I think she's starting to grow new leaves too. Any advice on how to move forward with this appreciated!
