You will not be allowed to join Freemasonry as is practiced mostly around the world, as regular mainstream and Prince Hall freemasonry is a men only organization or Fraternity.
Now, there is an organization called Le Droit Humain or Co-Masonry which calls itself a Freemasonic order that does allow women and atheist into their body. So you will need to search for those organizations as your only choices for women in a masonic-like organization. I have no experience with this organization nor do I have any contacts for you, and I do not know whether or not they have chapters/lodges in your area. You will need to research them on your own.
