If you are interested in the relative size of religious groups there, Presbyterians and Quakers were the largest groups in New Jersey. See the rest of the list, and more info about "The Middle Colonies as the Birthplace of American Religious Pluralism" here:

Answer 2

I am not sure I understand the question.

Do you mean the major religion in New jersey during colony times?

My GUESS would be some sort of Protestantism like Episcople.

Answer 3

NJ had several religious groups- there were the Dutch Reformed, British Anglicans, Presbyterians, Quakers, some Baptists, Mennonites, and other small sects, and a scattering of Catholics and Jews.
