I create two Extensions in my continer app. Do I need create diffierent provisoning profiles for these Extensions ?
Yes [1] [2].
An app extension has a different bundle ID than its containing app, and hence a different App ID. Each unique App ID needs a profile to authorise it to run.

[1] Well, there may be a way to avoid this on macOS but that comes with drawbacks. So, if you can do this on macOS, you should.
[2] Oh, and in some circumstances you can use a wildcard profile to cover both App IDs but, honestly, things are easier to understand if you ignore wildcard profiles.
