Stomach acid (or gastric juice) contains a number of components: the enzymes pepsin and rennin, mucus, and yes, hydrochloric acid. The pH of gastric juice is generally in the range of 1-3.
HCl by itself is a gas, and is called hydrogen chloride. The term hydrochloric acid refers to this gas dissolved in water. Hydrochloric acid can have any number of values for it's pH, depending on how concentrated it is. Highly concentrated HCl(aq) is extremely low pH; I don't know how low it gets exactly. You could calculate it if you cared; the strongest HCl(aq) is 38% by weight HCl.

| I moved the question about dynamite to the Organic Chemistry section. It's now it's own thread titled "Structure of Dynamite (Moved by Mod)".

If you are interested in finding the Ph of a substance use this equation.
-log[H[size=9]3[/size]O]
