No, he cannot. You would need to petition for your brother separately or your parents can do that once they become US green card holders (upon arrival in the US with their immigrant visas). If you petition for your brother, the process will be about 12 years. If your parents petition for him, it will be about 3 years as long as he is under 21. As soon as he turns 21, he will automatically go into a different preference category where the waiting times are about 6-7 years.
