what kinds of 和what kind of 的区别,后跟名词单数还是复数?

What kind of a person is he?(the answer is expected to be in the singular.)
What kind of people are they?(the answer is expected to be in the singular.)
What kind of dessert would you like?(the answer is expected to be in the singular.)
What kind of a teacher are you?(the answer is expected to be in the singular.)
How many different kinds of dessert are there?(several,the answer is in the plural)
How many different kinds of teacher are there?
All the above are correct usage of the word kind/kinds.
