HELP. Pictus hatchling

[concept3]

Ok, my second hatchling came out today. His clutchmate came out 5 days ago. I have a couple questions I would like to ask. Can I put them together right away? Can I leave him in the incubation chamber until he sheds?
And now to the HELP part. The first egg that hatched was completly empty inside. The second one has some yolk left in the egg. Is this bad? Did the yold sack rip off when he was leaving the egg? If the yolk sack did get ripped off does that mean he will die? I know I am asking lots of questions but this is my first clutch of eggs ever. Not trying to be annoying, I just worry about everything. Thx for any help/
