Beside group_vars there are host_vars, where you can define individual variables per host. Everything that is host dependent should be stored there and your username appears to fit there.

For hosts other than those two you can fall back to variables defined in group_vars or set a default value in your template:

{{ username | default("AxelFoley")}}

It's possible to set different variables in a number of different places. You should look at ansible's variable precedence documentation

The most common location for connection usernames is directly in the hosts file.

[webservers]
10.0.1.2      ansible_ssh_user=vagrant

[databases]
10.0.1.3      ansible_ssh_user=ubuntu

If your username variable is used to configure some service consumer, then you will should set it in group_vars or host_vars:

---
# group variable for webservers
username: abc

---
# host variables for 10.0.1.2
username: xyz

or if you need to loop over some application you are deploying, you may do it on a playbook level:

---
- hosts: webservers
  vars:
    app1:
      username: abc
  roles:
    - { configure_application, app: app1 }

- hosts: databases
  vars:
    app2:
      username: xyz
  roles:
    - { configure_application, app: app2 }
