"users" is an array of three things. So you have to either iterate over
the array as with something like "loop:", or index it as with
"users[0]['username']", "users[0]['homedirectory']",
"users[0]['shell']", or use some sort of filter that does the iteration
for you and selects list items that match some criterion. For example:
*- name: Extract matches for 'test'****debug:****msg: "User {{ item.username }} has homedirectory {{ item.homedir }} and
shell {{ item.shell }}"****loop: "{{ users | selectattr('username', 'equalto', 'test') }}"*
produces this:
TASK [Extract matches for 'test']
************************************************************************************************
ok: [localhost] => (item={'username': 'test', 'homedir': '/home/test', 'shell':
'/bin/bash'}) => {
"msg": "*User test has homedirectory /home/test and shell /bin/bash*"
}

I got the error below:
fatal: [ansible1]: FAILED! => {"msg": "The task includes an
option with an undefined variable. The error was: 'list
object' has no attribute 'test'\n\nThe error appears to be in
'/home/ansible/arrays.yml': line 7, column 7, but may\nbe
