Identification: What kind of Cactus is this?

I have 3 different cactus plants and I have been trying to figure out what they are called, I have posted pictures of them on my webshots page. Two of them are very similar and I think are the same plant, the other resembles a Christmas cactus. They are all three old plants and I hope to find out more about care and maintenance and if they bloom at all.

 

Ok...can you post the link to the webshots page? :)

Epiphyllum oxypetalum for the first one I believe.

Thanks, I believe this is correct, I have never seen mine bloom, but the rest of the plant does look the same.
