Answer
The answer is 9. If you are a boy, it would be 6 boys and 3 girls, but it you were a girl it would be 5 boys and 4 girls because you cannot be your own brother or sister.
10, the combination of 6 brothers and 4 sisters. Then each is guaranteed to have 5 brothers, 3 sisters. In the examples for 9 total, the girls in 6-3 would only have 2 sisters, and vice versa for the boys in 5-4.
