Hope its not too late :

Code:
du -skh /home/* > /tmp/usr_usage.tmp
echo " Login name  User Full Name  Used Space" 
while read line 
do 
Usage=`echo $line | awk '{print $1}'`
User=`echo $line | awk '{print $2}'| cut -d\/ -f3`
rlname=`grep $User /etc/passwd | cut -d: -f5`
echo "$User     $rlname     $Usage"
done </tmp/usr_usage.tmp
rm /tmp/usr_usage.tmp

But it looks like an assignment..
