I like all four names but especially Ryder. Ryder James sounds lovely! It's normal to worry a little about what your family and friends are going to think of your babies name, but they will always grow to love it because they will assosciate it with your beautiful boy! Rylan is another name you might like, it is a real name, although it's fairly uncommon (I have heard of a couple) and it means from the Rye Land. I think its great!
