The most commonly used term for happiness in Hebrew is "Simcha/שִׂמְחָה". Other variations of this word are not really used day to day. Other terms such as Chedvah and Orah are brought down in bibical sources, and have slight nuances that can be applied in more poetic terms. Orah, also means "light" while Chedvah refers to the happiness of being together with others.
