Maxima doesn't have a replot function (although it would be useful).
Replot is on the wish list.
plot2d accepts a list of expressions and plots all at once.
So you just have to figure out a way to generate the whole list of expressions.
e.g.
F(x) := x^p;
L : makelist (F(x), p, 0, 3);
plot2d (%, [x, -2, 2]);
Hope this helps
