Shall I use the simple past only for the following two questions (which refer to history)?

I included other doubts. Thank you.

1) Who were the King's Men?
2) Who was the real Macbeth.
3)What does Malcolm tell his soldiers to do when the army reaches (or reach) Birnam Wood?
4)Jasmine is pale-skinned and has got long, white hair and white eyebrows. She is an albino. Her sister Berth looks completely different from her.
5) She is dark-haired and her skin is also quite dark.
6) People sometimes stare rudely at Jasmine, make comments on (?) Jasmine's skin or say cruel things to her.
7) When she was younger, she got quite upsed by people's comments (on her) but now she has got used to them. She is much more confident (about herself?) and she is friendly when she speaks to people.

When you're referring to historical things, past tense is good. Present tense is mainly for references to actions in the play.

1. OK

2. add question mark

3. reaches (army is singular)

4. delete "got"

5. comma needed

6. make comments about Jasmine's skin,

7. When she was younger, she became quite upset by people's comments, but now she is used to them. She is much more self-confident, and she is friendly when she speaks to people.

1) Who were the King's Men?

In this question, you can use the simple past tense as it refers to a historical context. The King's Men is a proper noun referring to a specific group of people in history. Therefore, you can ask, "Who were the King's Men?"

2) Who was the real Macbeth?
Similar to the previous question, you can use the simple past tense here as well. Macbeth is a historical figure, and when asking about his identity, you can use the simple past tense and ask, "Who was the real Macbeth?"

3) What does Malcolm tell his soldiers to do when the army reaches (or reach) Birnam Wood?
In this question, you have the choice to use either the simple present or the simple future tense. Both are grammatically correct depending on your perspective. You can ask, "What does Malcolm tell his soldiers to do when the army reaches Birnam Wood?" or "What will Malcolm tell his soldiers to do when the army reaches Birnam Wood?" Both versions are acceptable.

4) Jasmine is pale-skinned and has got long, white hair and white eyebrows. She is an albino. Her sister Berth looks completely different from her.
These statements are describing the current characteristics of Jasmine, so you can use the simple present tense. For example, "Jasmine is pale-skinned and has long, white hair and white eyebrows."

5) She is dark-haired and her skin is also quite dark.
Similar to the previous statement, you can use the simple present tense as it describes the current characteristics of the person. You can say, "She has dark hair and her skin is also quite dark."

6) People sometimes stare rudely at Jasmine, make comments on Jasmine's skin, or say cruel things to her.
Since this statement is describing a general behavior that occurs in the present, you can use the simple present tense. For example, "People sometimes stare rudely at Jasmine, make comments on her skin, or say cruel things to her."

7) When she was younger, she got quite upset by people's comments on her, but now she has gotten used to them. She is much more confident and friendly when she speaks to people.
In this statement, you can use the simple past tense to describe Jasmine's past reactions to comments. Also, you can use the simple present tense to describe her current characteristics. For example, "When she was younger, she got quite upset by people's comments on her, but now she has gotten used to them. She is much more confident and friendly when she speaks to people."
