Video Recording Limitations on Free Account

I need to take interviews on the free Zoom iOS app on my Macbook Air. There will be multiple meetings (more than 50 maybe) and all of them will be recorded. There will be 3 participants in the meeting (including the host) and the meeting will be in gallery view. The recorded videos will then be edited and shown to the higher ups.

I need to know if this can be done on the free version of Zoom iOS app. Or should I go for the paid version?
