Firstly, Death was imprisoned by God at the first time, not Host of Heaven as I know. Lucifer bind him while he was in his coffin/upon releasing. There might be spells to bind archangels but not to kill them I believe. Spells are created by whom that is another mystery. Also Azazel was kind of off-guard when Dean shot him. He was depossessed thanks to John. He could dodge bullets by teleporting you know.
