Your welcome 
You’ve joined the right place, we have a lot of friendly and knowledgeable users on here.
You have some lovely snakes there 
Don’t take this as any sort of attack, I just want you and your animals to be happy…
It seems you have been dropped in the deep end in terms of equipment/animal ratio.
As soon as possible you need to get individual enclosures, with the correct heating equipment and thermostats for each snake… I don’t know if this is already your plans or not.
If your any good with DIY then check out this rack @chesterhf made recently. It would be a perfect place to start
