'A lot of' works for countable and uncountable; 'many' only for countable; 'much' only for uncountable.
"A lot of" works with both countable and uncountable nouns. It is informal and very versatile: "a lot of people", "a lot of money".
She has a lot of experience working with children, she has been a teacher for ten years.
We ate a lot of food at the party and did not feel hungry at all afterwards.
There were a lot of people waiting outside the stadium before the match began.
"Many" is only for countable nouns and "much" only for uncountable ones. Both are more formal than "a lot of" and tend to appear in negative sentences and questions.
How much time do we have before the lesson starts? I need to print a few things.
Many students find listening exercises harder than reading comprehension ones.
There is not much we can do today, let us wait until Monday to decide.
Common mistake
The most frequent errors: "I have much books" (wrong: "many books": "much" is for uncountables only), "There is many information" (wrong: "a lot of information": "many" is for plural countables only), and "She knows a lot of" at the end with no noun (wrong: "She knows a lot").
Trick to remember it
Quick rule
A LOT OF = any noun, natural in spoken affirmatives. MANY = plural countables. MUCH = uncountables. In negatives/questions = MANY or MUCH are natural.
Did you know?
The MANY/MUCH distinction reflects one of the most fundamental principles of English grammar: the distinction between COUNT nouns and MASS nouns (uncountable nouns). English applies this distinction with unusual grammatical rigidity compared to Spanish, where "mucho" simply adapts to gender. What is fascinating is that some nouns in English can be countable or uncountable depending on context, changing the meaning: "a coffee" (one specific cup = countable) vs "some coffee" (coffee in general = uncountable). So "many coffees" (several cups of coffee, in a café) is perfectly correct even though "coffee" seems uncountable. Context determines countability, and countability determines whether you use MANY or MUCH.
Exercise 1 · Pick the right one
There are _____ people at the market today. It's really crowded.

Exercise 3 · Form the word
'Few' has negative meaning (almost none); 'a few' has positive meaning (some, though not many).
'How much' asks about uncountable nouns; 'how many' asks about countable nouns.
"Some" is used in affirmatives and questions where "yes" is expected; "any" is used in negatives and neutral questions.
'A' is used before consonant sounds; 'an' is used before vowel sounds.
