We use "too much" with countable nouns. We use "too many" with uncountable nouns. "Too much" and "too many" are usually used for negative things.
Also know, how many is too many meaning?
Noun. Used other than with a figurative or idiomatic meaning: see one, too, many. (idiomatic) One or more servings too many of alcohol, leading to drunkenness. He's had one too many.
Additionally, which is correct there is a lot or there are a lot?
"There ARE a lot of animals" is incorrect. "Lot" is the subject of the sentence and it is singular. "Is" goes with a singular subject, "are" goes with a plural subject. "There ARE lots" is correct because the subject "LOTS" is plural.
Is way too much?
No, it's way too informal. 'Way' is one of the most common words in English and has more meanings and expressions than you can shake a stick at. Unless you use 'way' in its most basic and literal way ;-) it will be considered informal. I don't think it really has a 'formal' use.
Are a lot of or is a lot of?
We can therefore have either “are a lot of” or “is a lot of” depending on the noun. Mostly, we will use “There are a lot of” with countable nouns, when we discuss plurals, and “There is a lot of” with uncountable nouns.
