Number 12 looks like one of my favorite Florida natives, Thrinax radiata. It should have white seeds. Number 4 looks like either Livistona australis or Livistona chinensis.

Im 99% sure #4 is a chinese fan palm
Im also pretty sure #6 is a coconut palm (just not in fruit)
#12 looks to me like a thrinax also called a florida thatch palm.

All your guesses seem right except for the rubber tree one. I dont think its a rubber tree, but im not really sure what it is.

Very nice plants. Good luck!

1. No idea

2. Ptychosperma elegans (alexander palm)

4. Looks like chinensis to me

7. Thrinax, probably radiata, in deep shade

8. Clusia guttifera

9. I think it's actinophylla

11. Strelitzia nicolai

Thank you for your help everyone! There is a lot to learn about the different palms. Now I just have to put little plant name tags on each of them so that I remember them!
