You can also use Column and get rid of the \n's:

ListPlot[RandomReal[1, {50}], PlotRange -> All, Joined -> True,
 AxesLabel -> {"t (ps)", "(kcal/mol)"},
 PlotLabel ->
  Column[{"Total Energy", Style["Red: Velocity-Verlet", Red],
    Style["Green:Leapfrog", Green],
    Style["Blue: Accurate Velocity-Verlet", Blue]}, Center],
 PlotStyle -> {Pink, Red, Green, Darker[Green], Cyan, Blue},
 ImageSize -> 400]

You can automatically print the labels in the PlotStyle colours by doing 
something like

colours = {Pink, Red, Green, Darker[Green], Cyan, Blue};
labels = {"Label 1", "Label 2", "Label 3", "Label 4"};

ListPlot[RandomReal[{0, 1}, {4, 50}] + Range[4], PlotRange -> All,
 Joined -> True, AxesLabel -> {"t (ps)", "(kcal/mol)"}, PlotLabel ->
  Column[Prepend[
    MapThread[
     Style, {labels, PadRight[colours, Length[labels], colours]}],
    "Plot Title"], Center],
 PlotStyle -> colours, ImageSize -> 400]
