Oil it with "Crosman Pellgun oil", "RWS OIL" or "Gamo Pellet gun oil" Wipe it down. DO NOT USE Household oil or 3-N-1 oil. They will damage the gun. Put a drop in the barrel and run a swab through the barrel. If it's a C02 gun then put a drop of oil where the C02 bottle fits into the gun and charge the gun. If it's a springer type of rifle, put a drop of oil in the oil hole in top of the rifle barrel or in the loading chamber. DON'T over oil the gun.
Use a .177 cleaning rod and push the pellet back out of the loading port.

First, check to see that you have a BB gun, and not a pellet gun. Both pellets and BBs are made in .177 cal. A pellet gun will not shoot BBs (in most cases) If your gun IS a BB gun, you will need a gunsmith to check it for damage, stuck items in the barrel, etc.
It depends on the model and the caliber of the Pellet gun.

A pellet gun is not adequate for protection, and will get you arrested.
It all depends on the model and who made the pellet gun. I suggest that you re-post the queston with the model and make of the pellet gun to get an answer.
Any pellet gun should be handled like a real firearm. Yes you can be killed with a pellet gun under the right circumstances.
Nope. Pellet guns are fairly safe to use.
No. Even if it would fit in the chamber, there is no firing pin on a pellet gun.
