Read up on Text and Epilog in Help.

Something like
   

   Epilog->{ Text["p1", {x1,y1}, {-1,-1}],
                   Text["p2", {x2,y2}, {-1,-1}], 
                       Text["p3", {x3,y3}, {-1,-1}], . . . }

should do it.  

Changing the {-1,-1} values will change the offset.

Setting TextStyle->{-----} as one of the plot options will define the 
FontFamily, FontSize, etc for the entire plot -- or you can replace "p1" 
(inlcuding the quote marks) by StyleForm["p1",<options>] (no quotes 
around this) for each of the p1 strings.
