Answer 2

Answer 1

I agree with both your answers.

Answer 2

I agree with your first answer, but not your second.

The first "will" refers to willingness.
The second "will" refers to a future plan. See what happens when I re-write the dialogue without using the word "will".

Would you be willing to buy me coffee. If so, I plan to pay you back when you get here.

Note that if the "will" means one thing, then the meaning of the dialogue is somewhat silly.

Would you be willing to buy me coffee? I would be willing to pay you back when you get here.

or

Do you plan on buying me coffee? I plan on paying you back when you get here.

The first sentence is a request. The second sentence states a future plan.
