Can a PC connect to more than one Windows Phone 7 device simultaneously? If so, how?

I think you can't. Only to first connected device you can deploy application.
This question was discussed before: Connect multiple (two) windows phones to the computer at the same time and develop
Yes. Get multiple USB cords, one per device, and connect them all to the computer at once.
I'm not sure if this is what you are really asking for, though.
