The position of "be there"

Hello, teachers!
I think #1s are natural, aren't they?
Please let me know if #2s are also correct.
1-1. How much work is there to do by next week?
1-2. How many people are there working in your office?
2-1. How much work to do by next week is there?
2-2. How many people working in your office are there?
Thank you very much.
Best Regards.
