The first three pics and the last one I believe are dendrobiums. The fourth pic looks like phalaenopsis.
Dendrobiums like bight light where phalaenopsis do not like bright light. They are in sphagnum moss that I can see. That's fine but needs changing every year. Dendrobiums like to completely dry out before watering again. Phals like to get almost completely dry before watering.
Anyway, there's lots of information here on the OB, and you can check that out. All seem to be in great shape. You hit the jackpot! Both of those generally produce fairly often. Dendrobiums may need a rest during winter, but you will read about that.
I really like those pots in the fourth picture! I've never seen square clear pots with holes all around like that....way cool!
I can't help but feel bad for someone to have to leave their home and orchids behind like that. They must be going through such a difficult time. My heart aches for those being forced into that type situation.
