you need to fill a small container with moist substrate (eco earth, vermucilite etc)and put it in with the crickets, giving them a ramp to get to it.
the crickets with the long egg depositors sticking out the back of them are the females. they will start laying eggs in the substrate almost immediately. after about 24 hours take the container out and keep it moist every day, after a few weeks you will have tons of pinheads.
still do a google search on breeding crickets though, there is a ton of info on this more detailed that what i have told you
