4d Complaint -lovers in combination not hot. P?l?s . All I can think of is piles which is indeed a complaint but doesn't seem a very likely answer and in any case I can't see the wordplay.
5d It isn't entertaining having first played endless rock and roll. I have C?o?s?a?t so the answer looks like croissant . The word play eludes me but if croissant is supposed to be a (bread) roll , I think that is stretching the idea of a roll a bit far.
7d In old college, cheers for legendary queen. H???o?y?a. I am assume I am looking for a legendary queen but I can't think of an old college or what cheers is (nor a legendary queen).
Thanks
