In this paper, we discuss the structure of the unit groups of the semisimple group algebras of 10 non-metabelian group having orders 150, 160, 168 and 180, respectively. In particular, we consider the only one non-metabelian group of orders 150 and 180, two non-metabelian group of order 160 and six non-metabelian group of order 168 and study the unit groups of their corresponding semisimple group algebra. With this paper, the study of the unit groups of semisimple group algebra of all the groups up to order 180 is completed.
