ok, in your photostream: Pics 003 and 005 are either Cycnoches or Cycnodes... Pics 001 and 004 look more like Clowesia, but could also be Catasetum (I go more for Clowesia!)
check this thread and you will find some links with great information on teh culture of Catasetinae:

These plants are actually very easy to grow... follow the info given on the AOS links in the thread I gave you above and you will have no problems with them!
