There are a few things you need to know if you want to copy a group of people in Photoshop. First, make sure that the group is properly sized and that all of its members are correctly aligned. Next, select the Clone Stamp tool and click on one of the members of the group. The clone stamp will automatically create a copy of that member in the current layer. Finally, use the Move tool to move the clone stamp around so that it covers as many members of the group as possible.
