The only ones you can really skip are RE Coded and 358 2 Days. Although, if you find yourself enjoying the series, I recommend you to take a look at them. At the very least, you'll find Days pretty interesting.
Also, some people say that Chain of Memories is skippable too. I don't think that way. I believe that game has some very important story elements to help you understand a lot of what's going on in KH II. And personally I think it has the best overall story.
