Neither Jehovah's Witnesses nor Mormons follow standard Christian theology. There are some points of difference between Catholic theology and conservative Protestant, but they are generally very close...probably closer than some of the more liberal Protestant churches.
In general, the "regular" Christians, however, are all the people who have accepted a personal relationship with Christ, regardless of anything else. As a huge part of theology is resident in the relationship with the Holy Spirit, the points of disagreement are much diminished.
