You've only been here for six weeks. Your hubs need time to establish themselves in google search engines. Being featured on hubpages doesn't mean anything unless you're getting external traffic. Also, 13 hubs isn't very many in terms of adsense approval. Just focus on writing for now and then concern yourself with google adsense when you have substantial content.
P.S. This is misuse of the question feature. I recommend you consult the hubpages help page and/or search through the forums regarding this matter.
