How to turn lights on in a room at a time?

[dskogg]

Knowing that only 8 lights can display at one time, is there a way to group lights and  turn on and off these groups?

You can group select in the Adjust lights DBX and turn on or off the group while holding down the CTRL key.  But if you had a bunch of them the same you would have to name them all to keep track.  Might be easier to group select in plan view.
