How to iterate over register variables?

[J Dav]

I am trying to create an ansible play that 

1. Establishes if a user exists  on a host and records the stdout as a register variable. Referencing a dict file which contains what users should be on the host.
2. Creates a group for the user which will be created (with data from the dict) if the stdout == 0
3. Creates a user account (with data from the dict) if the stdout == 0
4. Copies over a sudoers.d template for a pre-existing ops group

And I saw at https://groups.google.com/forum/#!topic/ansible-project/htHzfr5HzQE that the register is turn into a list when combine in with_items. I can't seem to figure out how to iterate over a register variable list. Essentially, I'd like for my OpsTeam.yaml variables to correlate with the register variables and use that to determine if action should be taken. Note: this play currently does not work

Here is my code:

---

 - name: Deploy Users and Keys

   hosts: tag_AddUsers_

   sudo: yes

   vars_files:

    - "OpsTeam.yaml"

   tasks:

    - name: establish if user exists

      shell: /usr/bin/getent passwd {{ item.name }} | /usr/bin/wc -l | tr -d ' '

      register: user_exists

      with_items: users

    - name: create user group if doesnt already exist

      command: /usr/sbin/groupadd {{ item.name }}

      when: user_exists.stdout == 0

      with_together:

       - users

       - user_exists

    - name: Add in Ops sudoers.d file

      template: src=./ops dest=/etc/sudoers.d/ops

    - name: add users

      user: name={{ item.name }} createhome=yes group={{ item.name }} groups=ops append=no state=present shell=/bin/bash

      when: user_exists.stdout == 0

      with_together:

       - users

       - user_exists

Thanks in advance

​The list is within users_exists.results​
