If you got them as a Gesneriad Society gift package for the new member - they usually give you the list of what went into package.

2 medium size plants are probably Sinningia - silver leaf - S.leuchotricha. Tall weedy one - you need to wait some more to figure t out. I would say you can scooping them out and planting them in their separate small pots. Make sure you keep them covered for a week after repotting - and them open up. They will grow fater.

What is the soil mix you use? Looks unfamiliar.

Oh ok thank you! Yes I did have a list, I just lost it haha! I just used a regular potting soil.

I frankly do not recognize the scalloped leaf seedling. If your regular potting mix contains top soil... it can be a weed. Lets wait.

Oh... I hope not!

It looks like a gesneriad to me...in fact a LITTLE (not a lot) like achimenes.
