GUI, selecting a figure to close, if it exists?

I have a GUI that sometime at the end displays a new figure (handles.hf5). I create the new figure using:
handles.hf5=figure('position',[xpos, ypos, sz(2), sz(1)]);
When I run my GUI again, if this figure exists, I want to be able to close it. (sometimes I run the GUI with other options and no additional figure is required and so handles.hf5 does not exist.
I have tried the following but none work:
close all
allPlots = findall(0, 'Type', 'figure', 'FileName', [])
delete(allPlots);
and
if ishandle(handles.hf5)
close(handles.hf5)
end

In earlier releases, using ishandle() should work provided that the variable exists and has not been set to 0
if isfield(handles, 'hf5') && handles.hf5 ~= 0 && ishandle(handles.hf5)
delete(handles.hf5);
end
Note: close() can be intercepted by the figure's CloseRequestFcn callback, but delete() cannot be intercepted.

You are using R2014b or later, so you should compare to groot instead of to 0, and you should perhaps check ~isempty() as well.
I have not gone through your code otherwise; it is after 5am here and I am going to head to bed.
