Here are two to get you started:
- To provide ideal pH conditions for the enzymes pepsin and trypsin - proteases responsible for breaking down proteins in our food.
- To kill off any bacteria or other pathogens that are contaminating the food we eat.
After this, I'm stuck for ideas...
I'm not too sure that the first answer is completely correct. Pepsin is correct, but I believe that trypsin is secreted by the pancreas and enters the GI tract in the duodenum, not the stomach. Therefore, the contents of the stomach have been nuetralized to a pH of 8 (up from a pH of 2 in the stomach) by the time trypsin is exposed to them, which is trypsin's optimal pH.
Trypsin is also activated from trypsynogen (its inactive form) by enteropeptidase, which is an enzyme secreted by the cells of the duodenum, and also not found in the stomach.
Therefore, I believe that providing the ideal pH for trypsin is NOT one of the function of the stomach.
On another note, other functions of the stomach acid are to convert pepsinogen into its active form of pepsin, along with providing the ideal environment for pepsin activity; and to denature protiens so that their bonds are more exposed and easliy accessible by pepsin, trypsin, and chymotrypsin.

How do the epithelia of the esophagus and stomach relate to their specific functions?
By relating to their specific excretions. While they do share some excretory functions and products, the main function that they do not share is that stomach epithelial cells secrete hydrochloric acid.
Do you have acetic acid in your stomach?

What is the purpose of the secretion of acid into the lumen of the stomach?
The acid in the glandular stomach has two main functions. The first is as a microbiologic barrier - most bacteria, viruses and parasites are unable to survive the low pH of the stomach. The second is to start denaturing proteins by breaking apart the tertiary structure bonds and some of the primary structure amino acid bonds.
