One Direction is a band. To say that the band has a religion is like saying that Britain or the USA have a religion. Sure, they are dominated by Christians, but I am not sure whether you're asking me to say '40% of 1D is Christian' (made up figure) or state the individual belief of each member. Just to clear that up.
Another answerer has said: "Everyone in One Direction is Christian except Zayn, he's Muslim." (Answers.com)
Note also that biographies, of which I have read none, do not tend to detail religious and political views as these don't sell. Unfortunately I cannot be of any more use.
They are all Latter Day Saints!!

we believe in one religion and unity as humans.. we believe in the One God and only religion to be Humanism... we believe that humans are the only religion and our duties from God r only to love, live, help, and remember God.
Humanism is a philosophical belief that emphasizes the value and agency of human beings, their rationality, and their ability to improve themselves and society through reason and empathy. It rejects supernatural explanations and places importance on ethical behavior, critical thinking, and individual freedom. Humanists aim to achieve fulfillment, happiness, and meaning in this life rather than focusing on the afterlife.
