How do experienced cyclists know which gear they are in without an optical display?
Cadence mostly. The answer to your question is in the title. Experience.
Same way motocross riders know what gear they are in. The speed of the engine vs how fast they are moving.

What is this stamped metal piece that fell out of a new hydraulic shifter?
Providing the 7900 is the same, I’m sure it is but someone more qualified can chip in if it’s different.
How did it fall out ? Shimano have a proper tool for removing them.

Can a counterfeit Shimano chain be used on an authentic Shimano drivetrain?
The main problem is quality, in terms of dimensions and variance.
If you think its an 11 speed chain but someone has just repackaged some 10 speed chain, then there will be issues.
Likewise, if it ...

Can you use two different shifters (eg. Left-Tiagra,Right-105) on the same cockpit/handlebar?
The shifters on your left and right side don’t have to match. They can even be from completely different manufacturers.
On road bikes it can be problematic because when riding “on the hoods” (the ...

What are strong methods of linking two shifter cables together?
Don't
Personally I'd shop around and find a source of longer cables. Tandem brake/gear cables are exactly the same just longer, and shouldn't be 15x the price. I got some from Wiggle years ago and ...

Based on your description and photo, probably not. As long as it still functions correctly. That is the key.
So, if it still works and is not broken/cracked, go ahead and use it. Keep an eye on it ...

No, it's set up the right way. (In fact, because of the way the front and rear gear systems work, it's essentially impossible to set them up backwards: you'd have to re-engineer the whole system.)
