I haven't been able to find the syntax for loop + zip when combining more than 2 lists.

Since Ansible 2.5, as shown here, the following syntax replaces with_together with loop + zip:

- name: with_together
 debug:
 msg: " item.0 - item.1 "
 with_together:
 - " list_one "
 - " list_two "

- name: with_together -> loop
 debug:
 msg: " item.0 - item.1 "
 loop: "zip(list_two)"

My question is, whereas when using with_together, you could simply append lists, and reference them with iterating numbers, I haven't been able to find the method to use with loop + zip. I have tried:

loop: "zip(list_three)"

Without success.

You can append additional arrays inside the zip filter itself.

zip(list, list, list, ...)

For example:

- hosts: localhost
 become: false
 gather_facts: false
 tasks:
 - vars:
 list_one:
 - one
 - two
 list_two:
 - three
 - four
 list_three:
 - five
 - six
 debug:
 msg: " item.0 item.1 item.2 "
 loop: " list_one "

When run:

PLAY [localhost] *********************************************************************************************************************************************

TASK [debug] *************************************************************************************************************************************************
ok: [localhost] => (item=['one', 'three', 'five']) => 
 "msg": "one three five"

ok: [localhost] => (item=['two', 'four', 'six']) => 
 "msg": "two four six"


PLAY RECAP ***************************************************************************************************************************************************
localhost : ok=1 changed=0 unreachable=0 failed=0

You can append additional arrays inside the zip filter itself.

zip(list, list, list, ...)

For example:

- hosts: localhost
 become: false
 gather_facts: false
 tasks:
 - vars:
 list_one:
 - one
 - two
 list_two:
 - three
 - four
 list_three:
 - five
 - six
 debug:
 msg: " item.0 item.1 item.2 "
 loop: " list_one "

When run:

PLAY [localhost] *********************************************************************************************************************************************

TASK [debug] *************************************************************************************************************************************************
ok: [localhost] => (item=['one', 'three', 'five']) => 
 "msg": "one three five"

ok: [localhost] => (item=['two', 'four', 'six']) => 
 "msg": "two four six"


PLAY RECAP ***************************************************************************************************************************************************
localhost : ok=1 changed=0 unreachable=0 failed=0
