The english language stating the problem is already longer than your source code, I don't know if it can be made truly short. But you're right, grep | grep | grep | grep isn't terribly efficient. You could do it in several case statements and use ${#string} to get its length, or pile it all into an awk statement, which isn't terribly efficient itself, but better than five greps, and easier to see what you're doing.
Code:
if echo "$PASS" | awk '/^[_a-zA-Z]/ && /[a-z]/ && /[A-Z]/ && /[0-9]/ && (length($0) > 8) && (length($0) < 16) { X=1 } END { exit(!X) }'
then
echo "Password is OK"
else
echo "Password is not OK"
fi
