Dendrobium orchid water stress rehabilitation

[Nik]

Hello, everyone! I'm sort of new with orchids and gardening overall. I decided to take into my garden my mother's orchid that has been dying from underwatering. It's been about 2 months since I started the rehabilitation and there has been some progress. I decided to chop off a few dry stems (not sure of the proper name for it) and left the best looking stems with hope it can heal. 1 new stem has appeared and grew some leaves. But a few old leaves are still not looking great and I don't know if I should cut them off and just give it more time. And lately I've been thinking that I'm nor sure that this orchid is doing as great as I thought because I have not seen orchids look like this anywhere on the internet. I would love if anybody could give me some tips and opinions on this orchid. I belive this is a dendrobium orchid
