for i=1:n; set(handles.instr{i},'String','i'); end;

A little string searching combined with some struct functions will get ya what you need

handles.instr1 = randn;
handles.instr2 = randn;
handles.instr3 = randn;
handles.sheep = randn;
handles.cat = randn;
handles.dog = randn;
fields = fieldnames(handles)
fieldMatches = strfind(fields,'instr')
fieldInd = ~cellfun(@isempty,fieldMatches)
validNames = fields(fieldInd)
for i = 1:length(validNames)
    handles.(validNames{i})
end
