Where you think he lives. / How old you think she is

I want to know the following process is possible.

.

A-1. Do you think ~ + Where does he live?

A-2. => Where do you think he lives?

A-3. => where you think he lives. [Indirect question order.]

A-4. => This is where you think he lives.

Is it right?

.

B-1. Do you think ~ + How old is she?

B-2 => How old do you think she is?

C-3 => how old you think she is [Indirect questions order.]

C-4 => thirty-five is how old you think she is.

Is it right?
