It's simple, you need just call setValue on the child like this:

 ref.observeSingleEvent(of: .value, with: { (snapshot) in
        self.ref.child("USERS").child(email).child("user_name").setValue("new User Name")
    })

  ref.child("USERS").child(email).child("user_name").setValue("new user name"){
                                (error:Error?, ref:DatabaseReference) in
                                if let error = error {
                                    //error
                                } else { 
                                   //do stuff
                                }
                            }
                        }
