Ansible uninstall application, stop restart services

I am in need of creating a playbook that:

1. checks if application1 is installed - if fails then exit this host and move on to next host
2. checks if application2 is installed - if fails then exit & move onto next host
3. stopping application2 services
4. uninstall application1 - make sure application2 services are stopped before installing appliction3 - install application3 then
5. start application2 services
