Generally publishers ask authors to assign copyright of published articles to them. You will need to write to the publisher for permission to reproduce several copies of the article, or to reuse a significant amount of the work.
If the authors keep the copyright themselves, you have to get permission from each of the authors. Remember to cite the source of the original work regardless of who grants the permission.
