Help identify My Navajo Pieces

Hello, I just posted on the Intro & Chat but looks like I needed to post here. I recently purchased a “lot” of Native American Pieces. I think most are Navajo. Some had paper tags but I can’t verify the Artist’s Id’s on my usual search sites.
Pic 1 these pieces all marked HT (block Style) Pic 2
Pic 3 these pieces marked BT (block style) pic 4
Pic 5 these 2 pieces marked HB (HB are connected - the B formed off of the H, the right bar of H is also back bar of B)
Any help much appreciated! I’d like to resell these but don’t want to mis-represent.
Thanks
Teresa
