Yes. The firing pin is intended to make contact with a cartridge primer. When this doesn't happen, and it "lands" on an empty chamber, this causes resonance in the firing pin which can increase wear and eventually break it. A much better alternative to dry firing would be to use either spent cartridge casings or the "snap cap" dummy cartridges which you can find at most gun shops.

Agree with above. In addition, dry firing many rim fire weapons may dent the mouth of the chamber, resulting in misfires.
Yes, but it won't damage the gun in any way.
Yes. Recommend using a snap cap.
If you are asking about a "springer firing system" The answer is NO do not dryfire it. When you shoot a single cock springer rifle or gun with a pellet in the chamber, there is a moment where the piston actually slows down just before the pellet is fired down the barrel. If you have no pellet in the chamber the piston slams against the end of the chamber and this will eventually ruin the chamber. Dry firing a Co2 gun will not hurt it. You will just waist Co2.
Yes if you get hit with one it will hurt
No
No.
it is when you shoot something without it loaded like a bow if you shoot it without an arrow it will damage the bow
Hurt, Yes. Kill most likely not.
