Questions About Muslim Students and Daily Prayers in School

Assalamu alaikum, everyone! I've been learning about different religions recently and came across the practice of Muslims praying five times a day. From what I understand, these prayers usually take place at home or in mosques. I'm really curious about something: How do Muslim students manage to perform their Zuhr prayer while they're at school? Also, for the Friday prayer (Jumu'ah), do you find time to pray during lunch or is there another arrangement? (Just to share, where I am, there are a few Muslim students in my class, but they aren't very observant – none wear the hijab, for instance. One mentioned making up missed prayers at home, which they called kaza. Is that something common among you?) Another thing I'm wondering about is whether Muslim students ever face any bullying or negative attitudes because of their faith. If you're comfortable, I'd love to hear about your experiences. Jazakum Allahu khairan for your time and insights!
