Does any one have Idea to get these functionalities with the plugin wp-multi-network

I suggest you start over with that in the WordPress Support Forums of the WP Multi Network Plugin. I can only suggest this because I do not have any special experience with that plugin and I assume that it has DNS implications for the hosts you’d like to use it on.

Additionally you might want to make your question more clear and tell more about the setup you’re running (Server, Services, DNS and so on). Which steps did you have already done and the like.

But probably you find your answer already in that forum.
