multiple meetings at once

Question: what zoom plan would allow 3 different users under one account to run 3 different meetings simultaneously? How can I test to make sure this would work?

Background: my business is integrated with acuity calendar/scheduling app and I have 3 different team members who will need their own zoom meetings at once under one business account. 

For example: bob has a meeting with a client at 11 am, so does susie, and jamie- 3 different team members and 3 different clients all needing to meet via zoom under one account simultaneously.
