How Many Wires through joists?

Electrical - A/C & D/C - DoItYourself.com Community Forums - www.doityourself.com
I'm reading up and getting myself confused on what I can do to meet code.

In wiring recessed lighting in a basement project, I have setup 3 'sets' of lights (blocks of 4) on 3 way light switches, with the wiring all going to the bottom of my stairs and the other side, far end of the basement.

Is it ok to run the wiring for all 3 light switches to the lights through 1 hole in each joist?

Wiring is on a 15 amp breaker with 14/3 wire for the 3 way switches. I'm not sure if can squeeze 3 14/3 lines through a 3/4 hole, or would need to drill 1 inch.

The ceiling will eventually be sheet rocked over as well.
