in the bottom left corner is the Joey Palm i think or maybe a species in the ricuala family or Rhapis. Then you have another Rhapis of some sort in the middle. The other ones in the back i cant point out and then one that is barely in the picture with its leaf ends is probably a chinese fan palm.
oh and if you look RealPalmTrees.com has all of them. I think they are the only ones with the rare ones you are looking for and be able to buy them online.
