in terms of what silicone to use GE I or GE II you are going to always get varying answers. I personally use GE I for window and door. As long as its 100% silicone and has no additives for mildew / mold you are generally ok. Now if it was me, i would wait at least 2 days to be sure. You definitely want to make sure the smell is gone for one thing. I think GE II's smell goes away pretty quick but i would still give it at least 2 solid days. I'm sure you know by now the fumes silicone gives off while it is curing are pretty strong and i know when i was sealing a background in silicone i almost had to stop for a bit because the fumes were getting too strong for me and giving me a headache. Now if it can do that to a adult person, imagine what it could do to a tiny little frog. Better safe than sorry in my opinion. Do you have like a 10 gallon tank you would setup as a temporary enclosure with some substrate and some hiding spots, that's what i would do and leave them in the temp house for a solid two days just to be safe with the silicone curing. And i agree, i'd move them while they are sleeping and try not to disturb them.
