Yes they do.
The religion that does not believe in the Virgin Mary is Islam.

Those that are Christians - yes.
Yes, Christians believe in the Virgin Mary as the mother of Jesus, who is considered the Son of God in Christian faith. She is revered and honored in various Christian denominations.
No, as all catholic churches they believe in her
All Christians believe in the Virgin Mary. Believe means to think she existed. Now if you mean venerate (honor and pray to), then no, they do not.
The Eastern Orthodox Church believes in the Immaculate Conception of Jesus Christ's birth by the Blessed Virgin Mary, but it does not accept the Immaculate Conception of the Virgin Mary's birth.
The question is an oxymoron. To be considered a true Christian one must subscribe to a belief in the Nicene Creed which states ".........for our salvation, came down from heaven, and was incarnate by the Holy Ghost of the Virgin Mary, and was made man." So, if a cult or an individual does not believe in the Virgin Mary, one can not be considered to be a Christian.
