When using MRTG with RRD, you are restricted to two (and exactly two) datasources. This is a restriction of MRTG, not of RRDTool, so you could manually create an RRD with additional datasources - however, MRTG would not update or read them.
If you are using the Routers2 frontend for MRTG/RRD, then you can have multiples Targets, each with two datasources, and then define a Userdefined graph over them to make a single graph with more than 2 variables. The component targets can be hidden from the menu.
