Gabriel, for one (5)
I believe the answer is:
angel
'gabriel for one' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for angel that I've seen before include "somewhere in Islington" , "lady (very kind)" , "Guardian spirit; theatre investor" , "Investor in a theatrical production" , "Spiritual being - financial backer" .)
