Hi Dblues, welcome to the forum. The first orchid you have pictured there is a type of dendrobium. The second is a phalaenopsis. These both have different light and water needs. For information on your dendrobium, check out our member, Orchid_Man's post on What Type do I have

Care for your phal can be found here and lots of information can be found in our Orchid Links Section too.

Enjoy!

Cheers,
BD
