I noticed that there were still some watermarks left. So I guess ONR and OCW cannot remove these. I applied nanogloss in the watermark and removed some of them. I am not sure if it removed it or just hide it.

I guess I need cleaner wax or pre-cleaner wax muna for these watermarks before applying OCW.
ONR washing doesn't leave a lot of solution on the panel, so it should be fine - though what you can do is do a first drying pass with one MF to get most of the water off the car, then spray OCW and finish drying afterwards.

ONR and OCW won't remove watermarks. NanoGlos has some cleaning ability, so it can remove some of it, but you're right - a proper cleaner wax or pre-wax cleaner would be a better option.
