We use much, many and a lot/lots of to talk about (often large) quantities and amounts.
In conversation it is rare to use much and many in affirmative sentences. They are used in formal, written English but a lot of/lots of is preferred for both countable and uncountable nouns in conversation and informal writing. For example:
Does he have much money?
He doesn't have much money.
He has a lot of money.
Does he have many friends?
He doesn't have many friends.
He has a lot of friends.
However, much and many are a little more acceptable in conversation at the beginning of a sentence:
Much of our food is exported.
Many people drive too fast.
If you are not sure, use a lot of in formal and informal situations with countable and uncountable nouns for affirmative, negative and interrogative sentences.
