I am very sorry to hear this. Most prosecutor's offices have a victim's advocate who can help you understand the process in the court where your case is being heard. The advocate and the prosecutor are really the best people to tell you what the punishment could be. It will depend on the facts of the case, and particularly on the age of your half brother. Good luck to you.
The juvenile court can remove him from the family home until he has turned 21. Or he could be placed in foster care, again depending on his age and the circumstances of the offense. Or he could be allowed to remain in the home if the juvenile court determines that would be the best solution. At minimum it may require counselling until he is 21. After that he will not face custody unless he is civilly committed as a sex offender. No lawyer on this site can determine what the chances are of a particular result.
I gather this happened years ago if you were six at the time and are old enough to write this inquiry now. That may also be a factor, as well as whether he has a history of other offenses.
All of this needs to be asked by your brother to his attorney, who may be familiar enough with the facts of the case to predict a likely outcome.

If he pled guilty in juvenile court, the options are sending him to the Division of Youth Services or giving him probation. The attorney for the juvenile office should be able to tell you what they think and, specifically, what they are asking for as a sentence. I suggest you contact them and find out. You also have a right to be at all of those hearings and tell the Court what you think should happen to him.
I just answered your mom's question on here. He should. If you want to make sure - go to his court hearing and make sure to talk to the Judge about his sentence.
