I'll ID the ones I am familiar with, starting at the bottom of your list of pictures. The bottom-most plant is P. verrucosum, the next one up is a species of Dieffenbachia; the next up from that one looks to be Anthurium fausto-mirandae, which really does get quite large. I have several of them and they are massive. The next one up is too young to ID. Next up, there appear to be leaves of three different plants in the picture and I'm not clear on which one you wish to have IDd.
