Hi i have added my three sitemap in google webmaster tools and also uploaded in public_html/ but google webmaster tools is error and not indexing my url
please anyone tell me how to index more pages in google

What do you mean error? Mine's working perfectly, I just uploaded one .xml sitemap and it's all good.

I have a tool (paid) here that notifies major search engines about my newly created/uploaded .xml sitemap, so spiders can crawl it.

Is that an error or warning?

Google some times give me warning like “Link not followed because it is re directing to some other pages”.

This warning will disappear automatically after few days, there is nothing to worry about it. If you have some other issue in sitemap then elaborate them in brief.
