Hello Old Gal,
Glad to be of assistance!
4d. To give you the correct definition of the answer, I've always understood this to be a female spirit which proclaims a death in the family to which she is attached. I remember [from somewhere] the phrase "...the ******* wailing of a soul in torment."
5d. You want a five-letter synonym for lamp enclosed by an anagram of 'sets'.
9a. A four-letter word for 'praise' as a verb - the third letter being 'u' for 'universal'
16a. The chemical symbol for 'copper' followed by an an anagram of 'sorry'.
I hope that helps you without my giving you the actual answer because I don't think that's what you want me to do.
Kind regards,
