The acid found in the stomach plays a vital role in the chemical digestion of food. It activates enzymes which degrade proteins in the food, and causes other components of food to break-down.
Because it is compensating for the over-intake of food to digest.

Nope. Your stomach will produce more acid in response to food.
Stomach acid is more acidic.
The acid in the stomach has a lower pH than that of 'acid rain'. Therefore much more acidic.
Stomach Acid is Hydrochloric Acid mixed with other substances. The pH of hydrochloric acid is pH = 1. So it is a lot more acidic than a soda drink. Heaven forbid, but when you vomit, that horrible burning sensation is the hydrochloric acid from your stomach, refluxing into your throat/mouth.
No the hydrochloric acid in your stomach is far more acidic than vinegar. The stomach has a lining which is resistant to acid for this very reason.
If not the acid we use in our stomach. Diluted hydrochloric acid is what the body uses to begin digestion, but some other strong acid that was more highly concentrated than HCl would do great damage to the stomach.
The stomach secretes hydrochloric acid. The acid is produced by special cells called parietal or oxyntic cells. The pH of stomach acid is between 1 - 2. For more details see: http://en.wikipedia.org/wiki/Gastric_acid
No, the acid causes more of a stomach ache.
A more diluted acid.
Stomach acid will indeed dissolve some rubber balls. Certain rubbers are more susceptible to breaking down in stomach acid than others.
No. Vinegar contains acetic acid, a weak organic acid. The gastric juices in you stomach contain hydrochloric acid, which is a strong acid.
