No, its shelf life is virtually indefinite, due to its high acid content. With no refrigeration required, it's virtually self-preserving despite the fact that you may see some color change (especially in red wine vinegar), sediment settling or clouding; it's just an aesthetic change and shouldn't degrade the flavor or effectiveness. Vinegar will go bad if kept long enough, especially if it is exposed to the air. The acetic acid will gradually convert to aldehyde. The vinegar loses its acidity, develops an unpleasant odor and taste, and a texture that has been described as "ropey"
White vinegar is a pretty stable product. I do not know of any way that it can spoil.
Add vinegar. Vinegar contains ethanoic acid which will react with the milk and spoil it. Leaving it in a warm place will also make it spoil faster.
Pickles are usually made with a lot of vinegar, oil or salt. Any one of these will act as a preservative.

yes because it is still an egg, just with a different outer layer
no. it is a vinegar so it preserves itself
No, red wine vinegar does not have to be refrigerated. It will spoil over a very long time, but that is not related to the storage temperature, rather to its exposure to air.
Yes, white wine vinegar does not need to be refrigerated for storage. It can be stored in a cool, dark place like a pantry or cupboard. Refrigeration is not necessary as vinegar is a natural preservative and does not spoil easily.

Eventually, yes. It will also spoil if left inside the refrigerator, it just takes longer. Most vinaigrettes are made of nothing more than vinegar, oil and some herbs, all of which are shelf stable. The vinegar will never go bad, but herbs can loose their potency and oil will eventually go rancid. The onset of rancidity and the potency of the herbs can be maintained by keeping it refrigerated and the container sealed.
You can use vinegar to keep strawberries fresh for longer by mixing one part vinegar with three parts water in a bowl, soaking the strawberries in the mixture for a few minutes, then rinsing them with water and drying them thoroughly before storing them in the refrigerator. The vinegar helps kill bacteria and mold that can cause the strawberries to spoil quickly.
You mean canning or pickling? When you pickle something, you normally put vinegar in it. Some bacteria don't prefer to live in a slightly acidic environment (vinegar is a little acidic). So the vinegar will deter SOME bacteria from growing, which may prevent spoilage. When you can or pickle something, make sure to heat it very hot 165 degrees then close it TIGHT, immediately after you put it in the jar. This will prevent bacteria from living in the jar and spoiling the food! I would say that securely jaring and properly heating the food is the main reason why jarred or canned food items don't spoil.
