fid = fopen('1.txt','r');
indata = textscan(fid, '%d', 'HeaderLines',1);
yourdata = indata{1};
set(handles.edit1,'String',sprintf('%d',yourdata));
fclose(fid);

Did either answer work for you? If so, please accept the answer that works best, if not, please explain how the results of the provided code are different from what you want.

Your results in yourdata are almost certainly a column vector of values. When you sprintf() a vector of numeric values, sprintf() will put the results into one continuous row vector. You used %d format without any delimiters so the result would be just one long stream of digits (with perhaps an occasional negative sign mixed in.)
If you change from sprintf to sprintfc then the result of the sprintf will be a cell array of values, which will be suitable for setting the String property to provided that when you created edit1 that you created it with Max property at least 2.

set(handles.edit1,'String',sprintf('%d',yourdata(1)));
set(handles.edit2,'String',sprintf('%d',yourdata(2)));
set(handles.edit3,'String',sprintf('%d',yourdata(3)));

Instead of posting a new question and closing the old question, you should have explained what was wrong.
In this case, you need to set the Max property of your uicontrol element to allow multiple lines of text.
yourdata=9:12;
figure(1),clf(1)
handles.edit1=uicontrol('style','edit','units','normalized','position',[0.1 0.1 0.8 0.8]);
str=cellfun(@(x) sprintf('%f',x),num2cell(yourdata),'UniformOutput',0);
set(handles.edit1,'Max',numel(str))
set(handles.edit1,'String',str)
