Under the age of 18, "master" is the correct form of address, followed by his first name.
Aged 18 and above, "mister" is the correct form of address, followed by his last name.
For example: James Smith would addressed as "Master James" until his 18th birthday when he would then be addressed as "Mister Smith".
if he has an heir to his wealth (fathered a child/children), and only then would it be appropriate to be addressed as such by those servant to such.
Madam Emcee when addressed, otherwise Master of Ceremonies. There is no gender in the English noun.

No. Those are 2 different ranks. Master Sgt. is an E-8 while Sgt. Major is an E-9 in pay grade. A master sgt. is next in command before a Sgt. Major if he/she is sick or on vacation but is still addressed by the proper rank he/she wears.
After its replacement in common speech by Mister, Master was retained as an address for boys or young men. By the late 19th Century, etiquette dictated that men be addressed as Mister, boys under 8 years old be addressed as Master, and from 8 to the age of maturity males not be accorded courtesy titles. However, in more recent times it is not uncommon for high-school boys (and sometimes junior-high-school boys, but not, typically, younger) to be addressed as Mister, though some etiquette writers hold that the title Mr should not be used until the boy has left school. The title Master is much less frequently used in spoken language than formerly. However, Master is still used as the written form of address for boys of some undefined age, often regarded as under 8 in formal correspondence, particularly invitations to formal affairs.
Use the form of the recipient's name that he or she uses. For instance, one who uses John A. Harding III on his own correspondence should be so addressed in your letter.
