Need help - 2 Unknown Cattleya and 1 Dendrobium

[sthh]

It's going to be Chinese New Year soon, and in our part of the world, that means buying flowering plants to decorate the house.
I got this 3 plants from Malaysia, and the receipt simply state 2 cattleya and 1 dendrobium.
I really want to find out what they are, and I hope you can help.

I especially like the dendrobium. Here's some pictures.

Have been going through pictures of orchids in the internet, and there are some orchid flowers that look similar.
I think :
Dendrobium plant 1 is a Dendrobium cochliodes.
Cattleya plant 2 is a Cattleya Orange Nugget
Cattleya plant 3 is a Cattleya guttata.

I do have my doubts, anybody recognise them?
