Yes, Africa is located in all four hemispheres of the world: Northern Hemisphere, Southern Hemisphere, Western Hemisphere, and Eastern Hemisphere. It is the only continent that straddles all four hemispheres.
People say Africa is in four hemispheres because that's true. It straddles the equator (Equatorial Africa includes Gabon, Congo, Zaire, Uganda, Kenya, and Somalia), putting it in both the northern and southern hemispheres. And it straddles the prime meridian (which runs through Algeria, Mali, Upper Volta, and Ghana), putting it in both the northern and southern hemispheres.

Hemisphere means "half of a sphere". So in geometrical terms there are only 2 - Northern and Southern hemispheres. But we also refer to the Western Hemisphere (anything west of the Prime Meridian, usually used to refer to the Americas) and the Eastern Hemisphere (anything east of the Prime Meridian, sometimes referring to Europe, Africa, Australia and Asia) - but these are not true geological "hemispheres" - they are geographical for human purposes.
