In the Jain stories I found, King Shrenik is prominently mentioned with Queen Chelna, but I did not find a reliable Jain source there that gives a definite total number of his wives. So, from the Jain material available to me, the exact number is not clearly specified. ( jainknowledge.com)

If you want, I can also give the Jain story of King Shrenik and Queen Chelna in a simple form.
