Answer 3

I love it when I hear the Argumentum ad Populum, and then I'm directed to the adherents.org site.

They conveniently leave this part out:
"Groups which self-identify as part of Christianity include (but are not limited to): African Independent Churches (AICs), the Aglipayan Church, Amish, Anglicans, Armenian Apostolic, Assemblies of God; Baptists, Calvary Chapel, Catholics, Christadelphians, Christian Science, the Community of Christ, the Church of Jesus Christ of Latter-day Saints ("Mormons"), Coptic Christians, Eastern Orthodox churches, Ethiopian Orthodox, Evangelicals, Iglesia ni Cristo, Jehovah's Witnesses, the Local Church, Lutherans, Methodists, Monophysites, Nestorians, the New Apostolic Church, Pentecostals, Plymouth Brethren, Presbyterians, the Salvation Army, Seventh-Day Adventists, Shakers, Stone-Campbell churches (Disciples of Christ; Churches of Christ; the "Christian Church and Churches of Christ"; the International Church of Christ); Uniate churches, United Church of Christ/Congregationalists, the Unity Church, Universal Church of the Kingdom of God, Vineyard churches and others. These groups exhibit varying degrees of similarity, cooporation, communion, etc. with other groups. *****None are known to consider all other Chrisian sub-groups to be equally valid.***** David Barrett, an Evangelical Christian who is the compiler of religion statistics for the Encyclopedia Britannica and the World Christian Encyclopedia, includes all of the groups listed above in the worldwide statistics for Christianity."

(emphasis mine)

Answer 4

80% of the United States and one-third of the world. Around two billion in total.

Answer 5

There is no real number for true believers.
There are figures for what is believed Christians, those who claim the religion but do not believe.
Look it up on the web.

Probably 3 million true Christians.
