Of course, with variables you can do almost everyting.

  - debug: var=item
    with_sequence: end={{ number }}

ansible-playbook -e number=3

Please see loop control index_var on loop documentation

        usr: "{{ lookup('password', '/dev/null chars=ascii_letters,digits length=39') }}"

you are overwriting the variables on each loop, and then you are NOT
looping the shell action. Remove the set fact and use the lookups and
loop directly on the shell action.
