I think the most likely ones who tried to kill Jack in the past would be Will, Barbossa, Pintel and Ragetti...while Elizabeth is the one who succeeded. So it would be:
 * Why should I sail with any of you? Four of you(Will, Barbossa, Pintel and Ragetti) tried to kill me in the past, one of you(Elizabeth) succeeded.

I wouldn't have counted Elizabeth as one who "tried" to kill Jack, since she technically succeeded.
