I am new to DataStage...

Wondering what does it mean by running a job 2 streams, 3 streams or nStreams in Parallel Extender Edition of DataStage?

And how would you do that?

Thanks in advance

Have you read Chapter 2 of the Parallel Job Developer's Guide yet? That should answer this and any related questions. You may also find Chapter 58 edifying, as it goes into many examples of how to construct a configuration file, and therefore contains a wealth of information about processing nodes, node groups, resource groups, and so on.
