Maybe. I think it depends on the child and if the parents have instructed him/her in how to use and take care of the gun. Some children, at 10, are responsible enough to handle one, but others are not. It should be with the understanding that if the child shoots at another child or person, shoots at houses or windows, and doesn't use it correctly the gun will be taken away. This rule should be firm and solid with no bargains added by the child.

It all depends on the country and location where you live
technically yes but the adult in charge should know where the 13 yr old is and when they will be getting back etc... also they should go in a group not alone :)
They should not sleep without an adult somewhere in the house IMO.
