Quantifiers -much, many, a lot of, a few, a little

Lena: Welcome, cousin Tanya, to San Diego. I’m glad you’re here.
Tanya: I have heard that you have a lot of beautiful beaches in Southern California.
Lena: Oh, you’ll love them. I think that a lot of tourists come here just for the sea and sand.
Tanya: I know the sun gets hot. I’ll be sure to put on a lot of sun block and wear a hat.
Lena: Good planning, Tanya. It’s good to watch how much sun you get. A little sun on your skin is healthy, but too much sunlight isn’t good for you.
Tanya: There’s not much sun today, though.
Lena: Yes. There aren’t many days in July when we get cloudy weather, but today is one of them. That’s why I would like to us to see the zoo today. It’s a few minutes away from here. We can walk.
Tanya: I have heard it has a lot of wild animals. I want to see the snakes. You aren’t afraid of them, are you?
Lena: I got a little information about them from my friend who has one. Most of them don’t want any contact with people. They’ll be in cages, of course. There aren’t any snakes outside of cages.
Tanya: I’m going to the desert tomorrow. Will you be coming?
Lena: No. I won’t be around to go with you.
Tanya: I’m sorry. We won’t have much fun without you.

Um... I have a little question! How about 'a few and 'little'?

I think it should be:
..doing a few exercises...
Here "exercise" is a countable word, so it should be "exercises". Am I right?

Unfortunately, I don't have much time to watch a lot of YouTube videos on English lessons. Therefore, when I have a lot of time, I select a lot of educational videos and write a few comments.
I think a little hard work and doing a few exercise can develop my English.
I hope so!
