[Urgent] Need help, please respond

Hi, I have some urgent questions:

1. How to create match for member/user?
2. How to Re-generate bracket if not all participants loaded to bracket without creating new one?
3. How to renaming/change bracket round after it shows up (e.g round 6 change to semifinal, round 7 to final, round 8 to winner)
4. How to add image/video on match page and tournament page

Thanks
