Several of the words you list are also English words: guitar, algebra, elixir, tamarind, cafe, orange, arsenal, alcohol. When talking about English origins do we count those for Spanish or Arabic? ;)

Only guitar in that list comes to English from a Spanish etymology, the others come from Arabic via medieval Latin, French and Italian, not Spanish.
