It is possible to survive a gun shot to the head. It would depend which route the bullet took.
Only if you survive!
Depends on where you get hit .
I think it's highly impossible. It might be survivable, but it's extremely rare.
Head shot.
Yes.
In most cases, you can survive a pellet gun shot, but it will be painful, or worse. If you are hit just right (or wrong) you could die, so don't treat it lightly.
No vital organs hit.
It either hurts and you survive or it hurts and you die.
