Nickel-iron alloy is an alloy of nickel and iron, as might be inferred from the question. By combining nickel and iron in different proportions, we can manufacture a number of extremely useful alloys. Invar is just one of them, and it is important because it has the lowest rate of thermal expansion of any known metal or metal alloy (up to a few hundred degrees C). This makes for a good metal-to-glass seal in products that don't get super hot. Nickel and iron alloys have been essential in many applications in the manufacture of thermostats. The chances of your having at least one in your home are excellent. The "magic" in these nickel-iron alloys has been known for well over a hundred years, though they have been refined throughout all this time.

No. One is nickel, usually plated over a different base metal. The other is stainless steel. The object is usually made just of the stainless steel, with no plating. They can look similar in appearance, but the nickel plating can eventually wear off.
no nickel is an element, a metal
Yes. It's a metal.
no. nickel is a solid metal and not viscous material.
To produce nickel metal from ash, the ash containing nickel must first be processed to extract the nickel. This is typically done through a process called hydrometallurgy, where the ash is dissolved in a chemical solution to separate and purify the nickel. The extracted nickel can then be further processed and purified to obtain nickel metal.
Depending on who makes them and their quality, they are made from either silver, nickel, or nickel-plated base metal.

A nickel-metal hydride cell (NiMH) is a type of secondary electrochemical cell similar to the nickel cadmium cell.
Nickel nimh stands for "NIckel Metal Hydride"
