Yes, sheet metal can definitely be bent by hand, but it depends on a few factors: Thickness: Thinner gauges of sheet metal (like aluminum flashing or very thin steel) are relatively easy to bend with just your hands or simple tools like pliers. Type of Metal: Softer metals like aluminum and copper are much easier to bend than harder metals like steel. Size of the Sheet: A small piece of sheet metal is much easier to manipulate than a large sheet. Desired Bend Radius: Sharp bends are harder to achieve by hand than gentle curves. For simple bends in thin, soft metals, you can often get away with using just your hands, a sturdy edge (like a table), or basic hand tools. However, for thicker metals, larger sheets, or more precise bends, you'll likely need specialized tools like a sheet metal brake.

304 Stainless has a tensile strength of about 75,000 psi. Its yield strength is about 30,000 psi. Tensile strength is the amount of force required to tear or pull apart the metal. Yield strength is the amount of force required to begin to distort or bend the metal.
Sheetmetal Journeymen payscale is $20.85.
The R-value of steel sheet metal is relatively low, usually ranging from 0.02 to 0.04 per inch. This means that steel sheet metal is not a very effective insulator and does not provide much resistance to heat transfer. Additional insulation such as foam or other materials is typically needed to improve the thermal efficiency of structures made from steel sheet metal.
I think you are referring to a method of locating a nut in a piece of sheet metal. A rivet head nut is a nut with has a small projection not much thicker than the sheet metal to which you intend to fit it. This projection fits through a pre made hole in the sheet metal, and the small projection is peened over (deformed by hammering) to fix the nut to the sheet.
When a thin sheet of metal is hammered again and again, it becomes thinner and wider. This process is known as cold working or forging, and it increases the metal's hardness and strength. However, if hammered too much, the metal can become brittle and crack.
I can answer it generally. The guages were set up to be the area of sheet metal required to get a certain weight. With thicker sheet metal, you don't need as much area to get to the weight, so the guage number is lower.
Crown. The crown goes up. The idea is that the load will straighten it out. If the crown is too much, it will have to be used where smaller pieces will be used.
