You have not asked a question- and in the US, you are no longer a child on reaching age 18.
Depends on the gun, your age, and the laws where you are. And there are limits on anything. My grandson is 15, has a .22 rifle- which he can carry hunting. (He has a license, and the permission of his parents- and he lives in the country) He cannot take it to school, etc.
The law varies from state to state, and place to place in that state. For example, a minor (under 18) in one state that is enaged in ranching, and has WRITTEN PERMISSION from parents may openly carry- in other states, that person may not possess a handgun. Packing.org has a SUMMARY of state firearm laws.
No.
Very broad question- depends on where you were. I grew up in the countryside in the US, and it was not uncommon for a 12 year old to have a .22 rifle or shotgun- and to carry it hunting or shooting. It is still legal in most of the US- WITH PERMISSION OF PARENTS.

Reserved, philosophical mind.
The laws vary quite a bit from state to state, but in general, it is not illegal- but it IS restricted. When I hunt with my grandson, who is 14, he is a minor carrying a firearm- but it is legal since he has his parent's permission to hunt with me. In some states, a minor performing work as a rancher may carry a handgun- on his parents property, or with their written permission. The common factor seems to be with parent's permission. However, as I said- laws vary state to state- and country to country. You would need to check YOUR laws.
If both parents are O+ve, it means they have i allele, which is a recessive allele. For a person to have A+ve blood group, IA allele should be present. But in case of both parents being O+ve, there is no possibility that either of the parents carry the IA allele since it is a dominant allele. Thus the child would have to be O+ve.
Your question calls for an opinion. If a person is a law abiding, sane adult, there is no reason they should NOT carry a gun. Unless you think they should not be able to defend themselves from criminals.
All countries - once you have legal permission, allow you to carry a handgun.
A license or permit is issued.
Your question is not very specific about where you are, so the answer can only be quite general. Parents are usually allowed to travel abroad with their children. Depending on the country, the child must have a passport, or be registered in the parents passport. You should carry the birth certificate of the child, or a certified (notarized) copy of the birth certificate. Taking a child out of the country without permission of the other parent may be illegal in some countries.
