Sepoy, used of Indian soldiers in the English service, is the same as spahi, the French name for the Algerian cavalry. Both come ultimately from a Persian adjective meaning "military," and the French form was at one time used also in English in speaking of Oriental soldiery—

(Howell, Familiar Letters, 1623.)
Tulip is from Fr. tulipe, formerly tulipan, "the delicate flower called a tulipa, tulipie, or Dalmatian cap" (Cotgrave). It is a doublet of turban. The German Tulpe was also earlier Tulipan.
The humblest of medieval coins was the maravedi, which came from Spain at an early date, though not early enough for Robin Hood to have said to Isaac of York—
"I will strip thee of every maravedi thou hast in the world."
(Ivanhoe, Ch. 33.)
