Yes, either phrasing is correct.

2) OK

3) OK

4) Only when you are happy do (grammar rule?) you enjoy the pleasures of life.
I'm not sure what grammar rule you need. The words "do enjoy" make up the main verb of the independent clause in this sentence; "you" is its subject.

5) Pilgrims comes from all social classes with the exclusion of (except for ) the noblemen and the peasants.
Either phrasing works.

6)As a matter of fact, no noblemen would have agreed to travel with commoners, whereas no lower-class people could have afforded the expense of such a trip.

7) Chaucer doesn’t tell us his opinions about the pilgrims. He limits himself to describing them physically and morally.
In describing them morally, how is he not telling us his opinion?

8) The wind is personified as Zephyrus, the God of the west wind, which blows over each grove.

Chaucer describes his appearance and profession. The merchant is a representative of the emerging middle class in English medieval society.

9) Chaucer also wants to show how a person's profession conditioned the individual’s behavior.

Read and compare carefully ...

1) Yes, you can say "the most venerated English saint" instead of "the most venerated among English saints." Both statements convey the same meaning.

2) In this sentence, "describe" should be in the past tense to match the subject "Chaucer." It should be "Chaucer described the pilgrims as dynamic characters."

3) The sentence "Canterbury represents the end of human life" seems incomplete or perhaps unclear. If you are referring to the Canterbury Tales, Canterbury represents the destination or endpoint of the pilgrimage, not necessarily the end of human life. But if you have specific context for this sentence, please provide more information.

4) The structure of this sentence follows an inversion pattern with the auxiliary verb "do." It is grammatically correct to say "Only when you are happy do you enjoy the pleasures of life." This type of inversion is often used for emphasis or in formal writing.

5) The sentence "Pilgrims comes from all social classes with the exclusion of the noblemen and the peasants" is grammatically correct. However, you can replace "with the exclusion of" with "except for" for better readability.

6) The sentence "As a matter of fact, no noblemen would have agreed to travel with commoners whereas no lower-class people would/could have afforded the expense of such a trip" is grammatically correct. However, you can replace "would/could" with "could/would" for clearer expression. Both forms are acceptable, but "could/would" is more commonly used.

7) The sentence "Chaucer doesn’t tell his opinion about the pilgrims. He limits himself to describing them physically and morally" is grammatically correct. However, you can replace "tell" with "give us" to convey a clearer meaning. Both forms are acceptable, but "give us" implies sharing information with the audience.

8) The sentence "The wind is personified as Zephyrus, the God of the west wind, which blows over each grove. Chaucer describes his appearance and profession. The merchant is a representative of the new emerging middle class in English medieval society" is grammatically correct. However, it may be clearer if you separate the sentences or add a transition word between them, such as "Furthermore," or "In addition."

9) The sentence "Chaucer also wants to show how profession conditioned the individual’s behavior" is grammatically correct. It suggests that Chaucer aimed to illustrate how a person's profession influenced their behavior and actions.
