General zoom meeting questions

Hi,

I have a couple of questions about Zoom:

1- Is there a way where you can list the names of the participants in alphabetical order after you start the meeting?

2- Suppose you want to share a YouTube video during a Share-screen session while being muted. Would the audio stop when you mute your microphone? Is there a way where you can share the audio but mute your microphone?

3- How to force someone to unmute or join audio on Zoom.

4- If I was assigned as a Co-host for a meeting, can I change the settings of the meetings such as time date etc?

Thank you,

Huda
