I have the same bottle, albeit the contents have long since gone. From my recollection the wine was quite cheap at the time - so unlikely to be worth much now...if anything. The bottles are put on eBay now and then for between £20 and £60 but rarely sell.
The bottle will collapse when the bottle has heated air
Nothing important at room temperature and if the bottle is sealed.

Actually, an empty sealed bottle should expand slightly as altitude increases. At the altitude where the bottle is sealed, the air pressure outside the bottle is equal to the air pressure inside the bottle. When the bottle is transported to a higher altitude, the air pressure inside the bottle is greater than the air pressure outside the bottle (In other words: There are more air molecules per unit volume inside the bottle than outside). The increased air pressure inside the bottle relative to the outside pressure causes the bottle to expand slightly. An empty bottle would not collapse as altitude increases.
Practically forever.
It sinks unless it is sealed.
Yes you can IF you sterilize the bottle first before transferring anything into it.
When water is cooled, it shrinks. If the water is in a sealed bottle, it shrinks the bottle, too, collapsing it to some degree.
The fermentation process generates gas, enough to break or explode the bottle.
Via a sealed bottle or jug of varying size, typically.
