You can send it back to the manufacture to have it repaired or you can purchase a .177 Caliber cleaning rod and push the pellet back into the loading area.. The kit cost about $10 for the cleaning rod.
If you are talking about an air rifle. You need a .177 cleaning kit or thin ramrod. Push it back out into the loading chamber from the barrel. Do not keep firing it.

No they won't fit. If you force it, it will ruin the rifle.
If you are serious about air rifle .177 competition then there are several to choose from (See the link below) But I would select one of the Feinwerkbau P700 models.
If it is stuck in the barrel, you will have to get a .177 cleaning rod to push it back out. You can purchase cleaning rods from most any large sporting goods store like Basspro or Cabelas.
This is a .177 pellet rifle.
It all depends on the rifle, pellet and power source.
You mean What is the best PELLETS for an air rifle. This all depends on the current rifle you own. You can not use .22 caliber pellets in a .177 caliber rifle or vise versa. As for individual calibers them it's really up to you. .177 is more common, but I prefer the .22 because it is larger and has more knock down power. I even own a .25 caliber for hunting. Match rifles use .177 caliber But unless you plan to own a $600 to $2000 match air rifle I wouldn't lets that influence me to select a .177. As the calibers get bigger the pellets get bigger. Bigger pellets fly slower but fly straighter and hit harder. .177 pellets travel very fast but are more influenced by crosswind. Beeman actually makes a interchangeable barrel rifle, one is .177 and the other is .22. It's the model RS2 at around $135 it's gives you the choice of both barrels. I'm not trying to sell you on it just letting you know what is available.
It all depends on the model.
