I have to be short since I have a lot of things to do today. I think I can figure out a name for this noid vanda of yours. It is very pretty. It could be Asc. Princess Mikasa 'Blue'.
In term of caring for it, trim away the dead roots (most but not all), the dead roots retain moisture for the plant but too much, they encourage rot. Repot the plant into a basket just like your other vanda, use very loose medium or sparsely pack the roots in moss. That would help to increase the moisture around the roots. Keep the plant warm and very bright. Feed the plant at least once a week. It should do well.
