Guide our group alongside that female
I believe the answer is:
usher
'guide' is the definition.
(synonyms)
'our group alongside that female' is the wordplay.
'our group' becomes 'us'.
'alongside' says to put letters next to each other.
'that female' becomes 'her' (I've seen this in another clue).
'us'+'her'='USHER'
(Other definitions for usher that I've seen before include "Helper at wedding" , "Doorkeeper in court of law" , "Doorkeeper, escort" , "Theatre attendant" , "Cinema or wedding official" .)
