I believe the answer is:
friend
This clue is a double definition.
'companion' is the first definition.
(I've seen this before)
'quaker' is the second definition.

(Other definitions for friend that I've seen before include "Pal, amigo" , "Comrade for finder" , "Buddy, chum" , "Supporter of cause" , "Quaker - pal" .)
