If you are asking on how to make new point symbols (i.e. different ones than the default), I would suggest looking at the available Symbology help files. There are many existing symbols that come with ArcGIS, plus you can make your own within the software (and even buy some pre-made ones from third-party vendors, like fancy state-specific highway shields if you want).

However, if you are asking how to create new points, let us know, as that is a different topic (and has many ways to accomplish it).
