"how can i draw this 5 pieces?"
build one instance of the sphere (vertex -index buffers) and render them with different transformation matrix (MODELVIEW). rotation is not important only the translation counts here (glTranslate). with this you displace the spheres where you want them. same with direction keys which is not an OpenGL issue. grab pressed keys in your application and adjust the values in glTranslate. you can use GLUT to draw spheres.
