I assume that you have properties linked to each of these values.
In the callback, you can create a structure or a table involving all what you want, and write them to excel once.
For example,
tbl = table(yourApp.TimeTaken, yourApp.MaxHeight, yourApp.Horizontal, ...
'VariableNames', {'TimeTaken', 'MaxHeight', 'Horizontal'});
writetable(tbl, yourOutputDir);
In above example, I assue the handle of your app is your App, and the property names corresponding to the first three edit boxes are TimeTaken, MaxHeight, Horizontal.
If you didn't link them to a seperate property, you can manipulate through accessing the Value property of the corresponding text edit, e.g.,
tbl = table(yourApp.TimeTakenEdit.Value, ...)
