What the real full and birth names of the actors Adam West, Michael Keaton and Christian Bale? Thanks!?

I do not know if, Christian Bale is Christian Morgan Bale or Christian Charles Philip Bale. In the case of Michael Keaton, I do not know if, it calls Michael John Douglas or Michael Keaton Douglas and if, its birthday is in 9/9/1951 or 9/5/1951. Already Adam West, I do not know if, it changed the name of baptism (William West Anderson) or if only uses the Adam as artistic name. Please, they answer me! I wait answers!
