They were not equal.

Explanation:

In the feudal system people had different roles and obligations.

Nobles received land from their seniors (rulers) and were controlling it, taking care of the land and providing taxes.

Knights were serving to the lords, had the obligation to go to war when called upon...

Peasants had smallest rights. They were working on the land of nobles (manors) and sometimes were not even able to leave the land without permission. They received only small part of the crops they planted.
