It is difficult to answer this question without more information such as your brother's age and activity level. Generally speaking, a healthy weight for a 5-foot person is around 100 pounds, but this varies depending on factors such as age, body composition, and activity level.
If your brother is an adult, he may be considered underweight if his weight is below 100 pounds. However, if he is a child or teen, his weight may be within a healthy range. Additionally, if your brother is an athlete or very active, his weight may be lower than the average for his height due to increased muscle mass.
If you are concerned about your brother's health, it is best to consult a doctor or dietitian to determine if his weight is healthy for his age, height and activity level.
