Like you would call any other person.
You call a nurse with a bachelor's degree, a nurse. Such a nurse is higher paid than one without a bachelor's degree. Pay is the difference, not title.
A person with an Associate's degree is not entitled to a special form of address. Call them Mr or Miss or address them by their first names.
Yes, individuals with an Ed.D degree are typically addressed as "Doctor."
You call yourself what you presently are (a student). After completion of the MBA you will still be the same person, but can say you have earned an MBA which can be indicated on your business card. Such as Joseph Smith M.B.A. I must say, good for you. Completion of the MBA is quite an accomplishment. I applaud your effort!
Yes, although the title is rarely used outside of academia. The title of "doctor" is not exclusive to the Doctor of Medicine. All holders of research and professional doctorates are entitled to use title of "doctor".
