These words are exactly the same in english and spanish.Excellent=Excelente, Good= Bueno (Buena) , Passed=Pasado,Failed=Falló. Notes:If you are talking about tests or exams Passed=Aprovado,Failed=Reprobado. Sobresaliente, Notable and Suspendido have nothing to do with your words.

in this context "Excellent" should be translated as "Sobresaliente" and "good" as "notable" or "bien", "notable" is a higher calification than "bien" "aprobado" could be translated as "suficiente" too

depend of the context... passed has a lot of meanings, if you are talking about exam results is "aprobado", have a look at http://www.wordreference.com/es/translation.asp?tranword=passed&dict=enes&B10=Search failed is translated there as "reprobado" but anybody say it like this, at last in Spain, the most common it's saying "suspendido" if you are talking about exam results...
