I need to identify the intersection point of the blue graph where A is equal to the maximum value. And display the intersection with two lines. Is it possible?

Does this what you want? {maxA, pmax} = {#1, p /. #2} & @@ FindMaximum[Subscript[A, max], p]; Plot[{Subscript[A, max], Subscript[A, n0], Subscript[A, n2], Subscript[A, n3]}, {p, 0, 200}, PlotStyle -> {{Thick}, {Dashed}, {Dashed}, {Dashed}}, AxesLabel -> {p, A}, PlotRange -> {0, 0.007}, PlotLegends -> LineLegend[{n = 15, n = 0, n = 30, n = 60}], GridLines -> {{pmax}, {maxA}}]
