When New Jersey was a colony, Christianity was the dominant religion, which is the case to this day. Today, Catholics make up the largest religious demographic in the state.
Yes, there was freedom of religion in colonial New Jersey. The colony was founded as a haven for religious freedom and tolerance, and its constitution, the Concession and Agreement, guaranteed freedom of worship to all inhabitants. This attracted diverse religious groups, including Quakers, Baptists, and Presbyterians, who were able to practice their faith without persecution.
I'm pretty sure that the official religion was Anglicanism, but there were a number of different religious sects existing in New Jersey at different times before the Revolution. For example, as New Jersey was originally settled by the Dutch, there were a number of "Dutch Reformed" followers. Also, there were many Congregationalists (aka Puritans) who had migrated there from New England.
