Very difficult to tell from these pics. And I am going to throw out two names with no degree of certainty. In fact, with very little confidence. But you can look through Palmpedia for these and see if they match up. And I am only going to guess the genus.
1) Butia
2) Coccothrinax
The last two photos for sure is Coccothrinax, but i am not sure if is Argentea, Barbadensis or Proctorii, most probably is Bardadensis, i am not sure...
Hard to ID from the first two pictures but I'm not convinced about Butia. I'm thinking juvenile Elaeis guineensis, more commonly called African Oil palm.
