Spices were expensive and salt was so valuable that it was kept in a "salt cellar" or box. Only certain people were allowed any salt. That is where we get the saying "sitting below the salt" because only the people at the head table ( the rich) had any salt and everyone else who was "below the salt" was poor. The peasants ate basic foods and a lot of their diet was barley soup and bread. Wheat was also very expensive so only the very wealthy had any breads made with wheat. Just like today there are people who eat very expensive foods and there are people who don't. It all comes down to what you can afford.
Brewers were freemen, and were above serfs but below the nobility, in the middle class with other merchants and tradesmen.
Most people were poor and had only one outfit, and if they had a second, it probably looked like the first. The nobility had more, but not a lot, until later.
In medieval times, a Keep is a fortified tower found within a castle. It was usually the most fortified interior part of the castle and was used as a last line of defense, where the nobility would hole themselves up in with their guards should the outer castle be taken.
The nobility had the same religion as the commoners almost everywhere. In most of Europe, the Religion was Christianity. I know of only one exception in which the nobility had a different religion than the common people. Among the Khazars, who were Turkic people, there was a while when the nobility were adherents of Judaism, and the common people were Muslims.
Medieval ladies usually lived in manor houses. Sometimes they lived in castles. Especially in the later part of the Middle Ages, some members of the nobility had town houses in towns or cities, so a few ladies lived in these.
The three social classes of the feudal system were the nobility (lords and ladies), the clergy (church officials), and the peasantry (serfs and commoners). Nobility held land and power, clergy held spiritual authority, and peasantry provided labor and goods.
Both had a monarch who was above the nobility who was in turn above the peasantry and slaves.

Peasants, the birds.
Medieval bards sang for whoever could pay them. This was usually the nobility.

The Church and the nobility.

There was no medieval education for people other than nobility. People didn't know how to read or write. Priests taught nobility and a university system began in Italy.
The Renaissance nobles lived in cities and were active in trade, banking, and public life. This shows that the Renaissance nobles were smarter than the medieval nobles
The First Estate, speaking in terms of the Kingdom of France, was comprised entirely of The Clergy.
The nobility maintained the law.
