What roll does an accent on a specific word change its meaning,or how many letters can have an accent in Spanish'

There are homonyms in Spanish that need to be differentiated, so an accent is used, even though it doesn't change the pronunciation. Examples are mi/mí, si/sí, and que/qué. Look them up in the dictionary for their meanings.
There are general rules to this practice (such as, question words (qué and dónde) take the accent), but in general you just have to memorize.
Just one letter per word can have an accent, tops. Meaning change is different for each word, there is no rule.
Hi Bob - not an expert view - you need a Spanish speaker for that, but..... they change the stress within the word and on that particular letter. Not generally related to meaning, although there are examples of words where that is true. See this link http://spanish.about.com/od/spanishpronunciation/a/stress_accent.htm
