Re: it seems like InequalityPlot can only handle a color

<<"Graphics`InequalityGraphics`" 

Here the first line (bottom) is red (first style) and the second line (top) is thick (second style). If there were a third line it would be dashed and a fourth line would cycle back to red.

InequalityPlot[x+5*y<2,{x,-5,5},{y,-5,5},
    Fills->{Green}, 
      PlotStyle->{Red,Thickness[0.01],Dashing[{.05,.025}]}];

However, if you put your style elements into a list to create a compound style definition, all lines (top and bottom) share (cycle through single element list) the compound style

InequalityPlot[x+5*y<2,{x,-5,5},{y,-5,5},
    Fills->{Green}, 
      PlotStyle->{{Red,Thickness[0.01],Dashing[{.05,.025}]}}];
