Most cattleyas will not bloom as much as your phals and dendrobioms. You say that your cattleyas are getting larger, so when they get mature enough and it's the blooming season for that particular plant, you will probably get some blooms. It sounds like you're giving them good care. All it takes is some patience now. If you have large cattleyas that fail to bloom, they usually need more light.
Vandas are a whole different ballgame. I think it may be difficult to grow a vanda indoors in an open orchid basket. Generally vandas need a lot light, water, humidity and fertilizer. That's hard to provide indoors. I know there are some people on this forum that have had some succes growing them indoors and hopefully they can give you some tips for growing them that way. Good luck.
