The great advantage of Wicca, to most people, is that it can be anything the group wants it to be.Originally there were no Priests or Priestesses in Wicca. There was no real "format". Wicca is a very "loose" religion; Pagan in-so-much as it has nothing to do with the main, organised religions.Wicca is a name given to witchcraft by Gerald Gardner when he was trying to make witchcraft legal in Britain.
So, Wicca, really is anything you want it to be! There are a great many different "types" of Wiccans now in the world. Not all of them practise the same way!
So yes! There are groups similar to Freemasons. But do not mix them up!Freemasonry is not a religion.
