if you live in a close house neighborhood then no, but if your house backs up to woods then yes
Yes, whether it is legal is another question.
Only if it is legal. :)
No
It's not legal.
yes
It depends on how large your backyard is and the area in general. If the area you are in is in a wooded area, then no one should raise a flag at anything. If it is in an urban area, yes it is your property but there may be some who oppose this.
yes you can

No, as long as you only shoot at your property on your property.
No. Because, in order for you to shoot them you would have to get their permission to shoot them. If you accidentally shoot somebody inside your backyard without their permission, it is their fault for being in the yard with someone that has a paintball gun and is shooting it in the first place.
sorry buddy but its illegal
It is legal as long as you only shoot your property.
