The amount of money you save in fuel by depressing the clutch at stop lights is minuscule - you would be isolating the engine crankshaft from the input shaft on the transmission, and 'saving' a small amount of transmission bearing friction from being wasted. The energy and gas saved is not even worth trying to estimate.
Instead, you would be putting a lot more wear on your throwout bearing, leading to its premature failure, well before the friction material on your clutch actually wore out.
The transmission input shaft bearings are splash lubricated in several pints of transmission gear oil. The throwout bearing is lubricated for life with a fixed amount of low-viscosity grease - when the grease is gone, your TO bearing will begin to squeal when depressed and fail within a few thousand miles.
You can decide where you want to spend your money - on a clutch job tens of thousands of miles well before it should really wear out, or on a tiny amount of fuel.
If you shift your transmission and drive conservatively, and don't hold the clutch in at stop lights, you should be able to get anywhere from 50 to 150K miles, or even more, on one clutch (depending on vehicle type & weight, engine torque, loads pulled and flat vs level driving conditions.)

No, holding the clutch in will bring the engine to Ilde RPM`s, only taking off or upshifting will make the engine run harder and use more fuel.

Not a significant amount but it does wear the clutch if you rest your foot on it.
If stationary slip into neutral, a brake is cheaper than a clutch to replace

No, when you clutch it releases the engine from the Transmission ,thus the motor is not running anything but what runs off of the serpentine belt.

No it doesn't consume more, but it is putting a lot of wear on the clutch throwout bearing.

No, but it wears out the clutch prematurely.
