Technically the Bible mentions only Archangels, Seraph and Cherubin.

It will always be difference between angels because of what they have lived they won't have the same experience, some will be stronger than the others. For example castiel is stronger than the angels who are with Zachariah in the first episode of the the seaosn five. Yet he was just a regular angels like them. But Cas killed them. Or even Metatron, he says he was just an angel when God dragged him to His feet. Then he became the Scribe.
