No!
Apple allow just one firewire camera. And it is dv compressed video stream, that is not be recommended due to heavy on CPU in any way. If you plan to use a FW hard drive on the same bus you most likely get no video steam at all - you just oversaturate the FW bus.
I recommend using USB cams or capture devices to get multiple video inputs.
Also there is plenty of talk about this here and on VJForums.com
