True, but then Azazel is fanatical to Lucifer so its possible he may try if he thought Azazel would be able to free him, still its a gamble of long odds. As to you, its true there also names for the devil, however they are sometimes demons in there own right, I think its down to the belief all demons personify the devil in some way.
