2)What is meant by a blind via hole?
It is a hole that runs from an outer layer to the inner layer, but not through the entire PCB. These holes can be drilled mechanically or using laser technology.The image in point 1 shows a laser drilled blind via.

3)What is meant by a buried via hole?
This is a hole that runs between one or more inner layers. They are normally mechanically drilled.

4)What is the minimum pad size hole on the outer/inner layer?
This varies from manufacturer to manufacturer, but in general you can say that the majority of manufacturers can produce them as follows:
A = 0.15 mm
B = 0.20 mm
