Blondmyk!
If your plumeria are rooted cuttings like you say ( as opposed to seedlings) you could be expecting blooms.
I would recommend you plant them in the ground, those pots seem to be on the small size for the plant. You need to of course protect them from frost if you get any.
Also - have you been fertilizing?
The season is drawing to a close so I would guess that you should be working towards blooms next spring....
