it all depends upon the color and how you want to wire them. Red, yellow and orange LEDs consume 1.8V each, so you would be able to chain six of them in series together just fine

White, blue and green LED's consume 3.2V so you will only get three of them in series. The problem with series is that if one burns out, then they will all stop working.

If you go here: http://led.linear1.org/led.wiz

It will tell you how many leds you need and it will design the circuit for you.
