most of the ambient temps are below 80-85, so you might want to consider keeping your room temp closer to 75 and usign other methods to keep the ones that need a warmer enviroment warmer.
you could create a "warmer side" of the room using space heaters.
All the snakes should have some kind of suplimentary heat source to creating a "hot side" or baskign area in their cages. Flexwat is a great way to do this and I've heared it is very affordable.
Hope this helps a bit
