I believe that Cain may have also been blessed with those unique powers as the very first Knight of Hell. Lilith would be stronger than him, but he's very close to her in power possibly. I'd say that Lilith is the strongest, with Cain being her close equal and Alastair and Azazel being their subordinates.
