In the Unites States you have to be 18 to purchase a pellet or BB gun, but you can be any age to shoot it under adult supervision.
Can't be answered without knowing what state you are in, how old you are and what type of "gun" you mean.
It depends on where you are going to shoot. To shoot at a gun range I think the minimum age is set by individual states, but can be increased by rules set by the range. Normally, if you are shooting on property where it's legal for an adult to shoot and you have permission, as far as I know there's no restriction.
In some places, it is illegal. In others, it may be legal for a 12 year old to shoot under the supervision of an adult.
WITH the permission of your parents, and under adult supervision, any age where you are old enough to listen to, and follow instructions.
Not unless with adult supervision or without people witnessing he has a look alike gun
I think that it is not how old you are to shoot a gun it is the experience that you have with one.
Until you are old enough to complete a hunter safety course, and have a hunting license, you will need to be in the company of an adult to shoot. Once you are 18, you are an adult.

It depends on what type of gun. If it is a small to medium sixed gun (handgun or small rifle) 10 year old children can fire them. If you're looking to shoot shot guns, assault rifles, or a sniper rifle you may want to be over 13 or 14. If you're an adult you're fine shooting basically any gun.
WITH the permission of your parents, and under adult instruction, any age where you are old enough to pay attention, and follow instructions. My children and grandchildren started shooting with me at about age 10.
That would depend on the gun range and its operation rules.
