Short answer
PHP 7.4, 8.0, 8.1, 8.2 and 8.3. You can choose the version per domain in DirectAdmin and change it whenever you like.
Use the newest version your software supports — newer PHP is faster and still receiving security fixes. If a site breaks after an upgrade, switching back takes seconds, so it is a safe change to test.
