They are called "yardarms", and a schooner, no matter how many masts, generally only has 1 of them, though some do have 2.
A yardarm is either half of a yard; left or right. Together, (either a two piece or single piece) and across the mast with a square sail rigged from it, it is a YARD.
A schooner would have gaff's if she's so rigged.. A gaff runs fore & aft, behind the mast and is used to hang the fore & aft triangular sail that schooners use. Most these days have neither a yard or a gaff as they are 'marconi' rigged. If a 'schooner' had a yard (or yardarms comprising a yard) with squaresails on either or both of her upper masts she would become a more correctly called a 'topsail schooner'. If she's rigged with two yards and two square sails on the formast she'd be a Brigantine.
