ID's needed!

[mmursuli]

My neighbor gave me two orchids with no id's--she does that from time-to-time. She buys them in bloom, doesn't know how to take care of them and when they don't look "pretty," gives them to me. One of them looks like a dendrobium, but its cane is a lot thinner than the Dens. I already have...The other one I'm absolutely clueless about.
She also gave me a Phal. keiki...I told her not to touch it until it had at least 3 strong roots, but of course she didn't listen to me. It has two leaves and 2 strong, 2-inch roots. What are its chances of survival?
Below are the pics of the two orchids I need help IDing.
