Closed questions (Ja/Nein) and open ones. Interrogative particles, interrogative pronouns, interrogative adverbs.
To show interrogation in German, the order of the subject and verb is simply inverted:
Hast du Zeit?➜Ja, ich habe Zeit
Do you have time? Yes, I have time
In German, there are 2 types of questions:
Bist du müde?
Are you tired?
Wann kommst du?
When are you coming?
The "Ja-Nein" questions are those which do not have any interrogative particle and whose expected answer is "Yes" or "No" ("Ja", "Nein" or "Doch")
Sind Sie verheiratet?
Are you married?
When constructing the question, the verb moves to the beginning of the sentence (position number 1). Main article: the sentence
Open questions or "W-Fragen" have an interrogative particle at the beginning of the sentence:
Wo sind Sie geboren?
Where were you born?
The verb moves to the beginning of the sentece given that the interrogative particle does not take a position (Main article: the sentence)

"Wer" means "who" (it is used when we are asking about the nominative)
"Wen" means "to whom" (accusative).

This can be understood better with some examples:
For the verb "besuchen" (to visit), the people visited are in the accusative:

If we want to ask to whom what happened is told, we will have:
Wem erzählt er was passiert ist?
Whom is he telling about what happened?
