Given the following playbook, I would like to assign specific hostnames to every member of the hostgroup. Therefore, the name parameter needs to change for every instance in the hostgroup.
- name: friendly hostname
hostname: name=clusterXmember.1
How do I access the machine names from the inventory file? Specifically the current machine's ip, or the hostname?
As the playbook runs, I'd like the name param to be pre-filled with data from inventory. (generated from terraform)

The inventory name is accessible in different formats via the built-in variables inventory_hostname, inventory_hostname_short, and ansible_hostname. See the documentation I linked to for a description of each.
The IP can be obtained via the facts that are gathered for each host. You will probably want to use ansible_default_ipv4['address'] to get what you are looking for.
