The better preposition is "in."
Everything else is correct.
1. You should wear a swimming cap in the swimming pool.
2. You should wear a swimming cap at the swimming pool.
(Which preposition should we use? Are both OK?)
3. What is your number?
- My number is 22.
4. May I have your number?
- My number is 22.
5. What number are you?
- I am 22.
(Are all the questions and answers correct in Sentence 3 to Sentence 5?)
