syntactic analysis - Use of "Could you tell what kind of"

What is the correct use of the verb in the following sentences:

1. Could you tell me what kind of qualifications does a deputy coroner have?


2. Could you tell me what kind of car he owns?


3. What kind of underwear does he wear?

In the first and second example, I think the question is Could you, so the rest of the sentence should be written in simple form. The second example follows this "rule", however, the first insists on adding another interrogative form in does a deputy coroner have.

In the third example I think that What kind is the question, but there is an additional interrogative form at the end.

Which one is correct?

Thank you!
