No that is not valid syntax in a playbook. There is no way within a playbook to include vars that will apply for all plays.

If you want variables applied to multiple plays, and so multiple hosts hosts define them in your inventory or group_vars.

You could also pass variables from the command line, if you need variables to apply to many plays using the -e option.

Ssh – Ansible deploy multiple authorized_keys on multiple hosts

I would use a host variable "ssh_users", which states the users that need their host keys added.

- ssh_users:
   - bob
   - root
   - alice

Then, you have a seperate variable file that defines the name, key and state for each SSH user. Import that variable file, then call your original task pretty much as is.

Ansible run global variable

Yes, this is possible. When you set a fact with the set_fact module, this fact is accessible via "hostvars". So if you define your variable commandserver like so:

  - name: Set hostname of command server as fact
    set_fact: commandserver="{{ cs.stdout }}"

then you can access this variable in other included playbooks of the same play in that way (the debug module is just an example):

  - debug: msg="{{ hostvars['put the hostname in here']['commandserver'] }}"
