You can have a main ViewModel with other ViewModels, it is important to always set the datacontexts.

Yes, it's perfectly acceptable to have a hierarchical relationship (Parent / Child) between your ViewModels.

MainViewModel
  -> ViewModel 1
      -> ViewModel A
  -> ViewModel 2
      -> ViewModel B

These will usually reflect the hierarchical structure of the UI:

MainWindow
  -> UserControl 1
      -> UserControl A
  -> UserControl 2
      -> UserControl B
