@RoystonVaseySmegHead - as a veteran of foster dogs, sounds to me like you're doing a really good job.
If you think of it from the dog's perspective, they're had a lot of changes in their young lives - from wherever they were, to the pound or shelter and then to you. They don't know any of the rules, they don't know what's expected of them, they don't know what they are allowed or not allowed to do. So you're their beacon of security, and they've really only known you for a week or so - it's not surprising that they're anxious.
So if they sleep quietly and happily in a crate in your room, then let them get on with it. In the first couple of weeks out of the pound rescue dogs sleep a lot anyway, being lost is very stressful for them and a shelter is a very stressful environment. Sometimes young dogs act like young children who are over-tired, they behave badly because they're overwrought and can't settle.
So let them sleep and slowly transition them into another room if that's what you want to do, in few weeks. By then they'll have much more confidence in the routine, in you, in their situation and they'll probably settle quite happily. With the proviso that they're young dogs, so they are likely to chew things and make some trouble, because, puppy.
You can help establish their confidence by setting boundaries and being clear about routines. Give them a nice, predictable framework and they'll quickly learn it and it will help them be calmer. You might find that as they gain in confidence they start to test the boundaries a bit, so start off as you mean to go on. :-)
Really, it sounds to me like you're doing an excellent job.
