What is the difference between "too much", "so much", "very much" and "a lot"?

I'll use some examples because I don't know any Portuguese and it seems easier to explain it with them although they may not be clear enough.

He had too much alcohol. Now he is drunk. (He had more alcohol than what he should've had)

That's a lot of money! (That is a huge quantity of money)

Stop yelling so much! ( You are yelling a lot)

I like this dress very much. (I really like this dress)

I hope they help at least a bit :)

A lot - this is an informal phrase, that can be used to describe a number of anything, or a large amount of something.
