When you define a map in openlayers you should define one or more BaseLayer(but just one of them is displayed at a time). Upon these layer you could load as many overlay as you prefer.

Have a look here for the definition of overlay in OpenLayers.

This is an example of overlay with OpenLayers.

Anyway you could find a lot of samples just googling..
