I just installed the REHUB theme. I copied over the child themes to the wp-content/themes folder but they don’t show up in themes in WP. I just need to know what folder in WP they need to get installed to. The documentation I read wasn’t very clear about this.

REHUB theme has included child theme. So, child theme should work.
The best way to get this answer is Contact your purchased Theme Author.
