Hey, @AymanAhmed, let me add a little clarification to @Ohkawa‘s answer. 

Here’s the distinction: a user account is either Basic (no license) or Licensed.  A licensed account might be licensed as a Pro, Business, Enterprise, Educational, or Government license.

Bottom line is that the three of you should be licensed, and with only 3 licenses in the account, you’d get Pro licenses. Once you get up to 10 licenses, you move up to Business Licenses. They’re a little more expensive, but include a number of extra benefits, not the least of which is the ability of your account Admin to talk with Zoom Support by phone. 

i hope that helps!
