tasks:
- name: Check given file checksums
stat:
path: "{{ item.file }}"
loop: "{{ stat_results.results }}"
register: stat_results.results

- name: print and verify
debug:
msg: "Checksum PASS: {{ file_list }}"
when: item.stat.checksum == item.item.checksum.split()[0]
loop: "{{ stat_results.results }}"
loop_control:
label: "{{ item.stat.path }}"

In first task, you are looping it with variable stat_results.results which is undefined. you loop should have variable defined in verify.yml

Hi Kailash,

I'll always suggest to experiment with basic stuff and build the logic based on the understanding.  Below example can be used as reference on how to loop your verify.yml variable values which is list of dictionaries:-
- name: Check given file checksums
  stat:
    path: "{{ item.name }}"
  register: stat_results
  loop: "{{ file_list | flatten(levels=1) }}"
