Answer:
1) Monarch, 2) Lords, 3) Vassals, 4) Peasants.
Explanation:
The Monarch typically either held the most power, or was at least the figurehead of the society. This places them on the pinnacle of power.
The Lords swore allegiance to the Monarch, and with collectiveness, typically would receive some sort of protection under the Monarch umbrella. In return, they would have to send soldiers to help fight the Monarch's battles, as well as supply certain materials, depending on what they produce and what the Monarch's need.
The Vassals are such like Lords, in which they had small amount of land and infrastructure, and, as such in a lesser scale, would receive accommodations from Lords in exchange for their allegiance to the Lords.
Peasants are the most numerous and also ranked at the base of the pyramid, and typically was made up of farmers. These hold very little power, and sometimes were also attached to the land that they live and work on.
Of course, this pyramid does not include all classes, and the over-arching titles that can be used for multiple groups is not sufficient enough to place certain groups within these titles in the correct areas. Also, it is important to note that there may be differentiations from a hierarchy to another, but the over-all model is relatively the same.

Enclosure is also considered one of the causes of the Agricultural Revolution. Enclosed land was under control of the farmer, who was free to adopt better farming practices. Following enclosure, crop yields and livestock output increased while at the same time productivity increased enough to create a surplus of labor.
