I suggest you invert the order of your commands. Do each Plot first, without
displaying, and then Show them together:
In[1]:=
az = Table[
Plot[xyinterp[m][x], {x, -5, 5}, DisplayFunction -> Identity], {m, 1,
10,
3}];
In[2]:=
Show[az, DisplayFunction -> $DisplayFunction];
By the way, you might try using a coloring function for each plot so as to
avoid (or, at least, reduce it) the mess in the final display, e.g.
In[3]:=
az = Table[
Plot[xyinterp[m][x], {x, -5, 5}, PlotStyle -> Hue[m/10],
DisplayFunction -> Identity], {m, 1, 10, 3}]
