One of them is an antherium of sorts - the one with the big heart-shaped leaves (the vine). Although I do not know the exact species of antherium. You can pick those up at a local greehouse.

The broms with the variegated leaves (bars of dark and light green) are probably vriesias. They will get a sword-shaped bract/flower spike. The flatter broms with pink or red centres, and the smaller ones beside them (in the first pic) are neos. I think the full name is neoreglia. It would be almost impossible to identify the exact cultivar names, so you'll just have to look around at garden centres and on the Internet for others that you like.

Picture #2 looks like it could be a wandering jew. Normally they are purple and silver, but if grown in lower light, they will be green and silver.

Picture #4 is a tree fern of some kind. Not a staghorn. Looks a bit like asplendum nidus (sp? Bird's Nest fern), but not quite like it.

I don't know what the others are. Check the link below for lots of fern pics. They also sell them.
