I'm doing my Russian homework and just need to check that my answers are correct.

I have three in particular. I think they're right but I just want to be absolutely sure.

1. To ask 'Do you have any sisters or brothers?'
- У тебя есть сестры или браты?

2. To ask 'What is your brother called?'
- Как твоего брата зовут?

3. To ask 'Does she have a husband/Is she married?'
- У неё есть муж? / Она вышла замуж?

Thank you for any help!
