After remounting XFS filesystem with option "usrquota" you can issue the 
command similar to:

xfs_quota -x -c "limit bsoft=8g bhard=10g -d" /home

This command will enable the limits above for all users (-d flag), 
except users who have their limits existing already (usually ones who 
preformed fs operations).

For those who already have some limits set you can still can change 
these limits, but with individual command, say in the loop, like:

for i in `cat user_list`; \
do xfs_quota -x -c "limit bsoft=8g bhard=10g $i; \

I hope, this helps.
