To help this situation, you should get the boys neutered. They will all be happier and less stressed once they are over the operation. As for Bailey, it sounds to me like he is acting like a typical Siamese. Siamese cats are extremely loud. They mew a lot and their voices could wake the dead.
Some people love loud, social, Siamese cats.
If Bailey is bothering you, perhaps you could find him a new home with someone who will be delighted to have him. Bailey is unlikely to change and nothing you can do will ever shut him it. Loud is just the way nature made him. Bailey inherited the loudness and his brothers apparently didn't. Good luck with all your kitties.
