You've got some fairly good looking leaves, and small, but healthy roots on those plants. Any root that is plump, and turns green when it's wet is a healthy root that is working for the plant. When they have pointy tips like those, they're also growing pretty well, too. Pot them up!
What you use to pot them depends a lot on where you're planning to grow them. If indoors, (consistently drier and cooler) a mix of orchid bark with some sphagnum moss mixed in works pretty well, but if you'll be growing them outside (I see you're in Florida, like me?) just use the bark. The moss stays too wet. I have healthy Phals growing outside here, and they are mounted on bark mounts, and get watered almost every day. Good air flow is key, and the ability to dry out is also important to keep the roots healthy and the plants growing.
