Google can read the sitemap just fine. It has just not indexed the URLs yet. You probably wanna get some links to your site from reputable sites so it will notice the site more.
In the first image, the sitemap shows a tick next to it which means the formatting is OK.
The second one says "1,010 submitted URLs; 0 in web index".
The third has a "not found" error which is nothing to do with the sitemap. That usually happens when there is a problem connecting to the database and PHP (unhelpfully) adds a link to the "mysql.connect" documentation, which does not exist on your site.
