How does the mangkwan clan compare to other na vi clans in the story?

The question asks about the Mangkwan clan's comparison to other Na'vi clans, but no evidence has been provided that contains information about these clans. Without verified source material, I cannot confirm whether the Mangkwan clan exists in any story context, let alone compare it to other Na'vi clans. The Na'vi are the indigenous alien species from the film Avatar franchise, but specific clan details would require verified textual evidence from the source material.
