I tested on my system running RH9.1 and this worked fine:

whoami
   jonc

su 
cd test
touch y
chown jonc y; chgrp dan y
ls -l
   -rw-r--r--    1 jonc     dan        0 Mar 18 12:36 y

vi /etc/group
   dan:x:552:dan,jonc

exit

chgrp jonc y
ls -l
   -rw-r--r--    1 jonc     jonc       0 Mar 18 12:36 y

chgrp dan y
chgrp: changing group of `y': Operation not permitted

So you can gobble up files and give them your own group, but it looks
like it won't let you change group to another user - even though you
have rights to that users group.
