My friend had a brick that fell on him infront of his complex it gave him 28 stiches on his face could he sue the complex and how much around?

Your friend may have a cause of action against the complex.  To bring a claim, the at fault party must do something negligent.  Negligence here would require the complex to breach a duty of care to your friend, and because of that breach your friend sustains injuries and damages.  For example, if the complex was renovating the roof of the complex and failed to prevent falling materials (herein a brick) and the brick landed on a person causing injuries, the injured party could bring an action against the building.
