I took home these two different orchids from my office trash can. The one with thick leaves was out of the pot (ball of roots and moss) and all rinkly. I wateded once I got home and is looking betther. The one with skinny leaves (and roots) came in an opaque pot . the flowers where had dry edges and leaves where yellow. That was was potted in bark. I see some ok looking roots in one of them (from what ive seen in the internet) but i have no clue about the root health of the other one.

Is it possible to save any of there. and if so, what should I do? whats roots are healthy and which ones should go?

thank you!

The other one is this
