How do I do this?

How do I do this? And what plan is gonna be the best plan.

Here is a situation. I'd like to do online school service.

There are so many teachers like Teacher1, T2, T3... T1000

And there are so many students like Student1, S2, S3... S3000

For example, we have 5 classes at the exact same time (20th December from 2PM to 3PM)

Teachers are not permanent staffs (a part-time cram schoolteacher), so I don't give them a zoom license.

But of course, they need a zoom room for each teacher.

How can I make a room individually for each teacher at the same time, all by myself (alone)

If I make one room for T1 at 2PM, I can't make other rooms, right?

How can I make 5 rooms at 2PM.
