I have searched to add DISQUS plugin to my WordPress.com site but all solutions refer to WordPress.org self hosted blogs..Please let me know how to do it for WordPress.com site?
Sorry but you can't. There's a specific plugin that the administrators of WordPress.com approve to run in all WordPress.com sites. If you really want to run Disqus plugin you can try hosting your own site to a server and go to WordPress.org.
Yes you can ! Just install this via WordPress Plugin Installation http://wordpress.org/extend/plugins/disqus-comment-system/
Erlis method is working.just do it
Step 1: Select Add New under Plugins in the left panel of your admin. Search for "Disqus Comment System" and find the plugin provided by "disqus". Select Install.

No, it doesnt. WordPress.com only supports a specific list of plugins that they approve, and this is not one of them. Stop restricting yourself and buy some real hosting.

Follow those steps! If it doesn't work for wordpress.com , probably doesn't, since wordpress blogs have their own commenting system!
