The output of df shows availiable diskspace for mounted filesystems. The default RH install creates 3 partitions /, /boot and swap. Your /home, /usr and /var are part of / which is hdb2. So what you are asking is not possible unless you create additional partitions for the other directories. If you do want additional filesystems then the simplest solution would be to reinstall and create additional partitions. You can find out how much space is used in the other directories via the du command.
