at this stage you can turn the light off. they are already developed and teh ambient temp will be just fine for the duration. hope the one little guy makes it, they usually move a little when poked with something. i usually poke them with tweezers to make sure they are ok, but dont mick with them too much. i would just let them be until they decide to come out.
as for how your housing them i would seriously reconsider separate housing.
