Yes, all angels have different power levels but they still belong to classes, just as the demons did. No angel of the lowest rank has ever exceeded the strength of that from a higher rank unless by the aid of boosts such as numerous souls, divine weapons and/or an extensive battling experience (includes tactical use of stealth/surprise).

No regular angel has performed feats of that of the archangels' or zachariah's magnitude unless resurrected or promoted to do so. Yes, angels vary in power among each other within a class but are still unable to break through the existing tiers without outside assistance.
