Is there any way in which I can control all the computers in my wireless network?

For example, I have Linksys Easylink Advisor installed in the main computer, and the program shows the computers from my friends currently connected.

What do I need in order to stop a specific connection momentarily while keeping the others online?

Thank you.

Your wireless router should have a filter tool where you can block certain connections without affecting others. You may even be able to define days/times where this would be enabled.

For example, on my d-link, I can define when my younger daughter's computer can connect to the internet independantly of all other computers' connections.

You could always enable mac filter on your router or acces point and temporarliy remove the mac addresses you want to disable.
