Pages problem

Hi, it seems I have a problem, my Blog made some pages that I am not aware of. For example I have : http://blog.1dez.com/feed/mail.google.com
http://blog.1dez.com/mail.google.com
http://blog.1dez.com/make-money/hello-world/comment-page-1/mail.google.com
http://blog.1dez.com/make-money/hello-world/mail.google.com

They don’t show anywhere if i browse my blog , but i think this pages/links are somewhere …

My question is , where should I look in my wordprees to find where it stores pages and links so I can delete them manually ?
