If the question you are asking is, you want to remove the palms in your picture? Yes quite easily depending on a couple of things, how much labour you want to put into removing them, or can the palms be accessed by machinery. Looking at the photo you could cut them down and let them rot at ground level, job done and time is your helper. Or you could cut them down and manually dig the remaining trunk and root ball out with a lot of muscle involved. Last effort cut them down, get a machine in remove all the brick walls that are the large container they are sitting in, dig the root ball out, replace the whole site with a bit of flash landscaping and perhaps a better choice of palm or plants. Or just level the lot and a nice clivia border to match the garden behind the palms.
