Unless you have software that is designed specifically for multiple cameras, you will probably not be able to use more than one. While your computer can see the multiple cameras in Device Manager (or System Profiler in the Mac), there is no means to arbitrate the signal among them. This is typical for XP and OSX.
It sounds like you are trying to setup a surveillance system; this takes special hardware and is why these systems cost what they do.
As an alternative, you might be able to use multiple webcams and then link to them from separate webpages you have open on your PC. In this case, your browser just sees them as different websites.
