Pot them on now. Use a pair of scissors to *carefully* cut away the 
yogurt cups; there're millions more where they came from.

And keep an eye on them: they may need fairly regular potting on as 
the roots grow.

It is my understanding that monocot roots do not branch if the 
growing tip is injured, unlike dicots. Injure a monocot root and the 
damage can only be made good by an altogether new root growing from 
the basal plate (or equivalent organ) -- and that may not happen 
until next growing season. Hence the need to be much more careful 
with monocot seedlings, to handle them much more gently.
