What's the difference between "how many left" and "how much left"? Are they interchangeable?

Remember that "many" and "much" have the same meaning but cannot be used for specific nouns. Thus, they are not interchangeable and depend on the noun form. For example, "many" is used for plural nouns and "much" is used for singular nouns. Ex: How many pets do you have? => plural noun Ex: How much food do you want to order? => singular noun
