Lots of dendrobium roots stay white or light brown when wet, unlike phalaenopsis roots which turn that nice green when the velamin absorbs water. If the roots are firm and don't strip off when you run your fingers down them, they are probably fine. If you have new growth coming (that is the best time to repot) you should see green tips where the roots are growing.
The second one (last two pictures) is a dendro that was
one of a group of four I purchased on sale at a local nursery that were a bit overgrown and looked like they were on their way out.
One other didn't make it, I still have two in pretty good shape but no blooms in the two years I have had them (but I'm being very patient).
Right. Plants are small, just waking up from winter rest, and blasting out new roots. The other two, pot them up in fresh medium, once they start growing they'll probably be OK. Den-phals don't have a rest period, but spring is still a time for new growth.
