QL Models who&#;s names begin with either &#;O&#;,&#;P&#;, &#;Q&#; or &#;R&#;

Working thru my hard-drive I found all of the following models with the first name beginning with the letter 'O', 'P', 'Q' or 'R'. I think I know who they each are - but can other member suggest the correct names in the comments section? The porno-genius with the most correct suggestions will be a god amongst us mere mortals....
