How to reload Firewalld service using Ansible?

First of all use with_items for list of ports as below:

- name: Add port to firewalld
  firewalld:
    port: "{{ item }}"
    permanent: yes
    state: enabled
  when: ansible_distribution == 'CentOS' or ansible_distribution == 'Red Hat Enterprise Linux'
  loop:
    - 8080/tcp
    - 8000/tcp
    - 8090/tcp
    - 8040/tcp

You can also use the below code to enter ports if they are not fixed and use its as a variable:

- hosts: localhost
  gather_facts: no
  vars_prompt:
    - name: ports
      prompt: "Enter port(s) number"
      private: no
  tasks:
    - name: add port
      firewalld:
            service: "{{ item }}"
            permanent: yes
            immediate: yes
            state: enabled
      with_items: "{{ ports.split(',') }}"

and regarding reloading firewalld its mentioned here we can't reload firewalld using state parameter So use systemd module as below:

- name: reload service firewalld
  systemd:
    name: firewalld
    state: reloaded
