「新しい」 is the all-purpose default. In writing, pick 「新たな」 for a fresh start and 「新奇」 for the strikingly unusual. For things, 「真新しい」 is spotless brand-new, 「目新しい」 is what strikes you as novel, 「斬新」 is bold original design, 「新鮮」 is fresh food, 「新規」 is business-speak for new accounts, and 「若い」 fits young firms. 「古い」 is the antonym.
