Is it possible to create groups under groups in ms stream??

or is it possible to create channels under channels in ms stream??

No, I don't it works that way, with nesting groups or channels. What you can have is a group with as many group channels as needed, as a way of further organization:

A group with three groups channels

Also, videos can be put into one or several groups.  These two links go into much more detail on the different ways of organising a structure in Stream and examples, including with companywide channels and groups:

Yes @Cian Allner is correct.

You can have a Group with channels under it for organization. Or a companywide channel on it's own.

You can't have groups within groups.

@Avinash Parmar - Does the groups with channels under it work for you? Or is there something in your scenario that doesn't cover? What is the use case you are trying to cover?
