8. You can repeat steps 1-6 for different Revit files and create NWC files that can be then appended into a single Navisworks integrated model. You could even append to the same Navisworks integrated model, not only NWC files coming from Revit models, but any other 3D models with a format suitable to be appended into Navisworks (e.g., dgn, dwg, etc.)
