Run this
all_fig = findall(0, 'type', 'figure');
close(all_fig)

Thank you, but don't take my wife. Your codes works for me, just a quick question:
What does the 0 represent? I try to figure out with help findall, and find nothing helpful...
Thanks, and take my wife now.

0 is the graphics root object, which is also returned by the groot function, so you could do findall(groot,_)

Just to add another approach,
Set HandleVisibility to on when you create the UIFigures. That way their handles will be visible to gcf() , close all, etc....
uifigure('HandleVisibility', 'on')

If you want to keep some figures you can close a subset of them if you keep the figure-handles in an array. If you modify your creation to something like this for all call to uifigure:
if ~exist('uifig')
uifig = uifigure;
else
uifig(end+1) = uifigure;
end
if ~exist('uifig')
uifig = uifigure;
else
uifig(end+1) = uifigure;
end
% ...etc
% then you can close some suitable set of them, or all of them
% closing all:
close([uifig]),clear uifig
% closing some:
close([uifig([1 3])]),uifig([1 3]) = [];
