Multiple archetypes

[Undone]

I'm sure this has been answered somewhere but can you take multiple archetypes on a single character?

If so can I take Oath of vengeance as a paladin and take divine hunter?

You can have as many archetypes as you like as long as they don't replace or modify the same class features.

In your example, both replace Aura of Justice so RAW you cannot use them together.
