A drill operating at ultrasonic frequencies (>20 kHz) will usually employ a hard abrasive powder to actually do the drilling. The drill bit (which could be soft) vibrates back and forth at a high frequency, and grinds the substrate away with the abrasive.

Yes, you can, but you will have to order it from the company that made your drill.
On a pedestal drill the workpiece is static and the drill is in a vertical position and rotates. On a lathe the workpiece rotates but not the drill, and the drill is in a horizontal position.
Tungsten is a major component in those drilling bits.
Yes. Ultrasonic waves can pass through metal. The only difference between "normal" sound waves and ultrasonic waves is that we cannot hear ultrasonic waves. However, they behave the same.

Carbide steel or diamond tips.
A drill bit (hand or machine) is designed to drill a hole through either wood or metal material.

Titanium is Not the best metal for drilling but from a type of carbon steel

Use a titanium bit for best results. Clamp the piece of copper to a piece of wood if possible, so that the wood supports it from underneath, and give the drill bit a place to go once it goes through the copper. Wear safety gloves and glasses to keep from being injured by small shards of metal. When you drill through it, use a fast spinning speed with the drill, but don't apply a lot of pressure, just allow the drill bit to slowly work its way through the metal.
Both will. Carbide tips will last longer but the black ones will also. The key is to run the drill slowly and use oil.
(trick question? find a more narrow wall.) They sell drill bit extensions - metal rod. OR measure carefully and drill from the other side. Or find a drill bit that is long enough.
Any case or bag that impedes an ultrasonic sensor will be opened and its content examined. Security standards do not allow certain kinds of containers to pass through uninspected.
An ultrasonic jewelry cleaner can effectively clean watch bands using just water and ultrasonic waves.
