四角 is the common word for 'square', while 角 alone is less frequent and often appears in compounds.
角行 is the full name for the bishop piece in shogi; 角 is the abbreviated form used in casual play.
The kanji 角 originally depicts an animal horn, extended to mean 'corner' or 'angle'. The reading かく is the on'yomi. The various specialized senses (shogi, music, astronomy, currency) derive from this basic meaning of 'angle' or 'corner' through metaphorical or historical extension.
