The general term is "debtor" for someone who owes a debt. Other near-synonyms include borrower (which is someone who owes money which he has taken by way of a loan, not as a result of a purchase, fine, legal judgment or other financial obligation) and mortgagor (which is a borrower who has secured his or her debt with a mortgage, normally against land).
A good example of a word with multiple meanings is the word bill. It can mean the beak of a bird, a statute in draft before it comes a law, a piece of paper money or a statement of money owed for services rendered (for example, a receipt that one receives after eating in a restaurant).
