Well, you *could* do something like the following, treating each set of
coordinates as a separate list so that each one gets its own PlotMarker.
coords = {{{-5, 5}}, {{8, -3}}, {{6, 8}}};
strings = {"String 1", "String 2", "String 3"};
ListPlot[coords, PlotMarkers -> strings, PlotStyle -> Black,
PlotRange -> {{-10, 10}, {-10, 10}}]
But why not construct your own Text graphics primitives? For example:
list = {{-5, 5, "String 1"}, {8, -3, "String 2"}, {6, 8, "String 3"}};
f[x_List] := Graphics[Text[x[[3]], {x[[1]], x[[2]]}]];
Show[Map[f, list], Axes -> True]
