Why did the Demon Tablet  say Metatron was an Archangel when he was in fact a regular angel?

If even Death couldn't kill the bearer of the Mark of Cain, how was Cain killed? Shouldn't he have not survived?

Why couldn't Dean, as a demon/knight of Hell, retain Super Strength and Telekinesis while bound, when Cain could? Shouldn't he have been equal to power to Cain, being transformed by the mark as Cain was?

Did Gadreel have any connection to the Grigoi?
