Bolt of uniform Strength means that the entire length of the bolt is subjected to same intensity of stress,that is stress in the shank portion and the threaded portion are same.this is achieved by reducing the diameter of the shank to core diameter of the thread.

It may gall if it is of the same material as the bolt. It may need to be lubricated, that will prevent this; also, if over-torqued it may gall or strip the thread.
UNC stands for "UNIFIED BOLT THREAD COARSE" UNF stands for " UNIFIED BOLT THREAD FINE"
He is right. A fine thread would be 1/2-20.
A, the half inch bolt has 13 rows of thread in one inch.
general use coarse thread bolt is correct. 1/2 inch bolt. 13 threads per inch.
The first technician is correct, it is a coarse thread. I'm not sure there is a bolt called 12-13 so I am assuming you meant 1/2 - 13. Wich would be a bolt 1/2 inches long. The diameter of a #13 unc bolt would be ( 13 x .013in ) + .06 = .229 inches in diameter.
No. The coarse thread UNC screws will not thread into the fine thread UNF holes. UNC must be used with UNC and UNF with UNF.

A thread gauge is a tool used for identifying the particular thread on a bolt or screw. The gauge will have several blades with saw like teeth of different sizes. You match a particular gauge to the thread which will then tell you what size thread it is. gauges come in various pitches to match different screw threads. UNF, UNC, Whitworth, Metric etc. Each has a different pitch angle and thread per inch or millimetre.An image of a thread gauge can be seen HERE
Your meaning is not clear. - If you are going to tap the threads in, use a 7/32 drill bit. If you want a hole that this bolt will slip through, use a 9/32 drill bit.
It is a standered fine thread bolt, Grade 8
