Yes you can, as long as one of the active skills of the card you level up (PR Hades) is the same as the cards you use to level it up (Hades) is the same.

Some cards with two active skills have feeders for both active skills, in that case you need to use 5 cards with the same active skill, you cannot mix and match.
