Can someone give me a quick lesson about this term

Answer 1

everyone in the country had an overlord, except the king

The grandest people had the king as their overlord.

Answer 2

each noble was either a lord or a vassal, and sometimes both

a powerful noble became a lord when he gave pieces of his land to others whom he could trust. in return for the land, these people called vassals, promised loyalty and military service to their lord.
