My Brother has a warrant for not going to a DUI hearing in Phila, PA. He lives in NJ. If arrested can he be extradited to PA?

He will almost certainly be arrested. Whether or not he is extradited is up to county in which his case is filed. It is their decision whether to spend the money to pick him up. If they choose not to, the warrant will not go away. He will simply be arrested over and over (and held for a week or so each time) until he takes care of the case. Obviously, he needs to hire an attorney who practices in the county in which the case is filed.

See the answers to your other post. He can bwe detained.

He could be extradited since dui is a crime in Pa. He should retain a Philadelphia criminal defense attorney to get the warrant lifted and defend the case. He may qualfiy for ARD, a diversionary program that could keep him from a permanent criminal record.
