'That's the student council president?' 'Isn't he cool?' 'I mean, is he beautiful?'

Literal

''That [subject-が] student-council-president?'' ''Cool not-is?'' ''[or rather-つーか], beautiful-person?''

A school-scene reaction. つーか is a very casual/rough contraction of というか ('or rather, I mean'). 美形 (びけい) literally 'beautiful form' is a noun for someone with a strikingly beautiful face — used for men who are androgynously beautiful rather than classically handsome. かっこよくない? is the negative of かっこいい ('cool') as a tag question, same pattern as the じゃない tag question.
