Apply the Clear function to a symbol to clear values and definitions for that symbol, e.g.: Clear[x]

This ran fine on a beat-up old loungebook with k=100... (BTW - this does not directly answer the "How do I fix this problem doing things this way..." aspect - sometimes the answer is just "...don't do it that way..." when there's a more direct path to the desired results.) k = 100; size = 4; start = 1; end = 300; howmany = 1; If[howmany =!= All, ...

ClearAll[t, al]; set[t_, al_] := {{Cos[t], al + Sin[t]}, {2 Cos[al] + Cos[t], 2 Sin[al] + Sin[t]}, {al, t}}; ParametricPlot[set[t, al], {t, 0, 2 \[Pi]}, {al, 1, 2}, PlotRange -> All] Table[set[1., al], {al, 0, 2. \[Pi] - \[Pi]/36, \[Pi]/36.}] // TableForm Taking one parameter only in the Table, it works.

On further look, your ParametricPlot expression is a bit odd. You have something like : ParametricPlot[{ f[t] , g[t] , h[r] } , {t,trange} , {r,rrange } .. ] By supplying ParametricPlot with two independent variables it thinks you want to plot regions, yet none of your functions depends on both variables. Try this: testpara[\[Alpha]_] := Show[{ ...
