What is the voltage and current required by each laser?

That will tell you the resistor you need.

Here's a schematic (theres an error in the instructions, take battery voltage minus the Laser voltage and then divide by the total current to find the resistor.... not battery voltage divided by total current):

Hi, I think we may have the same laser pointer. I've just hacked this type of keychain laser pointer and created a huntorials for it. Please check if this helps:
