I left out a few last things I need to prepare. Thank you.

1) Who is Caliban? How did Caliban behave towards Prospero when he first arrived on the island? Does he regret his behaviour now? What does he wish?
Caliban is the witch Sykorax’s son, a strange creature of brute intelligence.
2) (When Prospero arrived in the island, Caliban showed him all the features of the island, the freshwater springs, the saltwater pits, the barren places and the fertile ones. He curses himself for doing that. He wishes he could use all the magic spells of Sycorax against him and plague him with toads, beetles, and bats.)
3) He is the only subject Prospero has in his kingdom. He reminds Prospero that the island belongs to him because he inherited it from his mother, the witch Sykorax.
4) Prospero was his first king, and now he pens him up in that cave (he keeps him shut up like
a farm animal) and doesn't let him go anywhere else on the island.
5) What did Prospero and his daughter try to teach him? What did Caliban do to spoil their relationship? How do both Prospero and Miranda call him?
6) In what way is The Tempest different from Shakespeare’s previous plays? What is the most striking feature of the play?

To answer your questions:

1) Who is Caliban?
Caliban is a character in William Shakespeare's play "The Tempest." He is the son of the witch Sycorax and is known as a strange creature with brute intelligence.

To find this information, you can read the play itself, specifically the character descriptions and dialogues.

2) How did Caliban behave towards Prospero when he first arrived on the island? Does he regret his behavior now? What does he wish?
When Prospero first arrived on the island, Caliban showed him all the features of the island, including freshwater springs, saltwater pits, barren places, and fertile ones. However, Caliban cursed himself for doing so and now wishes he could use all the magic spells of Sycorax against Prospero and plague him with toads, beetles, and bats.

To understand Caliban's behavior and wishes, you can read Act I, Scene II of "The Tempest," which features a conversation between Caliban and Prospero.

3) What is Caliban's relationship with Prospero?
Caliban is the only subject of Prospero's kingdom on the island. He reminds Prospero that the island belongs to him because he inherited it from his mother, Sycorax, who was a witch.

You can find information about Caliban's relationship with Prospero by reading various parts of the play, such as Act I, Scene II.

4) How does Prospero treat Caliban?
Prospero treats Caliban as his subject and keeps him confined in a cave, not allowing him to go anywhere else on the island. Caliban feels oppressed by Prospero and compares himself to a farm animal that is shut up.

This information can be found throughout the play, particularly in scenes where Prospero and Caliban interact.

5) What did Prospero and his daughter try to teach Caliban? What did Caliban do to spoil their relationship? How do Prospero and Miranda refer to him?
Prospero and his daughter, Miranda, tried to teach Caliban language and civilized behavior. They wanted to educate him and make him more like a human.

However, Caliban's behavior towards Miranda, wherein he attempted to violate her, spoiled their relationship. Due to this incident, Prospero and Miranda often refer to Caliban using derogatory names, such as "freckled whelp" and "moon-calf."

This information can be found in Act I, Scene II and Act IV, Scene I.

6) In what way is "The Tempest" different from Shakespeare's previous plays? What is the most striking feature of the play?
"The Tempest" is different from Shakespeare's previous plays in several ways. It is considered one of his later and more mature works.

The most striking feature of the play is its magical and fantastical elements. The presence of spirits, the use of magic, and the island setting all contribute to creating a unique atmosphere in the play.
