No ... but their may be an age requirement.
Nope. Pellet guns are fairly safe to use.
Yes.
This all depends on the country and location where you live.
Contact your local police
In most states you have to be 18 to purchase an air gun, BB or Pellet, (Not a Air soft gun). It's best to check local ordnance's first. No license is required.
It is possible, Yes, But it depends on the caliber, Weight of the pellet, the FPS of the gun. I suggest using a Pellet rifle not a pellet gun. I suggest a head shot using hollow point pellets. Also a license may be required to hunt the goose
It would help if you stated the model and the condition of the pellet gun. Without some information it is not possible to answer you.

Can not be answered without knowing how heavy the pellet is, how fast it will be leaving the muzzle, pellet shape, location where it will be shot.
In most states, you just have to be 18 years old.
If you are 21 and have no criminal record there is no requirement to have a carry license however you do need one is you wish to carry concealed.
