Try the crate in the bedroom. All my puppies spent their nights in a crate right next to the bed. I could mutter a reassuring word or reach out and stick a couple of fingers in the crate if I had to, but I can't remember having to do that more than a couple of times the first few nights. After that if they fussed in the crate, it meant they had to go out, and that only lasted for the first few weeks. Of course different puppies have different sensitivity levels, but you could at least give that a try.
Puppies are used to sleeping with littermates. It's not surprising they need some help to transition to alone.
