Holy Fire can hurt archangels and probably destroy the vessel, but it can t kill them. Remember when Castiel throw Holy FIre on Michael.

You are right about the angels that see God.

Raphael could not smite Seraph Castile because he was overpowerd by souls, and Lucifer when he had Vince Vincete as a vessel said that he could smite everyone including Seraph Castiel , Crowley and the boys with a snap of his finger , but he doesnt do that because what is the point , they are no threat to him.

Lucifer aloso used angel blade when he fake-kill Crowley, true he did not need that , that was just the plot to make Crowley trick him. Lucifer snap his fingers and kill all those AU Angels ( angels that have wings and full power ) with easy, he did not snap his fingers and kill Castiel , Crowley and the boys because writers plots.
