Yes, anyone can become a Christian if they accept Jesus Christ into their heart as their Lord and Savior.
If the question is asking whether an atheist can turn from Atheism and embrace Christianity, the answer is a resounding "Yes!" A classic example of this was CS Lewis (The Chronicles of Narnia) who turned from being an avowed atheist into a prolific Christian writer with a profound understanding of theology. CS Lewis was an intellectual giant, and he had many heated debates with his good friend JRR Tolkien (Lord of the Rings),who was a Christian. Finally, Lewis could not dispute the evidence any further, and accepted the truth of Christianity.
Yes. Many atheists were once Christians.
There have been many. If you count children, then every Christian was once atheist, since babies are not born believeing in a god - they have to be taught that.CS Lewis is one of the better known people who have become Christian after being atheistic.
