That man, creative, friendly and warm (6)
I believe the answer is:
hearty
'friendly and warm' is the definition.
(hearty can mean friendly)
'that man creative' is the wordplay.
'that man' becomes 'he' ('he' refers to a man).
'creative' becomes 'arty' (I've seen this before).
'he'+'arty'='HEARTY'
(Other definitions for hearty that I've seen before include "Enthusastic" , "sporty type" , "Vocally cordial in earthy way" , "Loud and cheerful" , "Stalwart" .)
