This piece of code
for i in /fix1/*
do
echo ${i#/fix1/}
ls $i/fix2/|wc -l
done
gives you the number of files and directories in each /fix1/*/fix2.
This another
for i in /fix1/*
do
looser=${i#/fix1/}
echo $looser
find /fix1/ -t f -user $looser | wc -l
done
gives you how many regular files has each user in /fix1. You can also use
find /fix1/$looser/fix2 -user $looser
if you know every file belonging to user1 is in /fix1/user1/fix2
I advice you to read "Bash advanced scripting guide" and to google "Example
scripts" or something like that. Man pages for awk, sed, find, grep and shell
are perhaps not very easy to read.
Or you can try

Have a funny scripting!!
