The Varnas ordered from top (highest status) to bottom (lower status):
Brahmins (priests, teachers and scholars)
Kshatriyas (warriors, administrators and rulers)
Vaishyas (merchants and farmers)
Shudras (laborers)
Dalits (<em>avarna</em>)
As you can see, the Varnas are fundamentally 4. However there are certain tribes that don't belong to any Varna, such as the Dalits which are classified as <em>avarna</em>.
Hope this clears things up!
