Nearly none of these belong in the law, no matter what word you use. The one exception is that we need to way to refer to tribal lands, tribal law, tribe membership, and similar. I think "tribe" and "tribal" are normally the best terms for this. In some cases, "North American Aboriginal" or "Hawaiian Aboriginal" would be more appropriate.
