Looking at the roots, some look okay to me, but there is one maybe two fans that I would be concerned about because they look like they have very little roots and look a bit dried out to the point of death. Roots looked chopped off on at least one of them. Especially the smaller fan in plant 1. I think the rest could be salvaged, but I would let the seller know and tell them you want a refund for any that die. (I know there may not be much you can do about a bonus plant.)
