The higher the number the higher the viscosity.
Viscosity tells you the speed at which the oil will flow. The lower the viscosity the faster the oil will flow at 210 degrees fahrenheit as in an SAE30 weight oil. Any oil with a W attached such as SAE 10w30 means the oil was tested at a cold temperature and will flow as a 10 weight when it is cold and then performs as a 30 weight at 210 degrees.
The ease with which it flows or how thin or thick it is. the more solid it is the higher the viscosity. As in Oil the thicker it is the higher the viscosity machine oil low viscosity, gearbox oil high viscosity.
I dont know why you would want to do that. The multi viscosity and straight weight oils wont mix and the multi viscosity oil will be expended faster when it is at its low end. If they happen to reach the correct temperature together, they will flow as united and become the same weight but never be homogenous.
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
SAE30
Single viscosity is high quality oil. Mulit-viscosity oil is used for in the winter.
In my beetle I run SAE30 oil in winter, SAE40 in summer. I change oild religiously at 3K minle intervals without fail. Aircooleds don't seem to like multi-viscosity oils. If it's below freezing out the SAE20W oil is called for.

Mixing oil weights is a NO,NO.

No, absolutely not.
