Ah, part of the problem is that you want different dropdowns in the same question.
To reproduce the first question in your example survey:
1)
Set up your survey to use JavaScript.
2) Create an Array (Numbers) question with a minimum value of 1 and a maximum value of 5.
3)Add your x-scale and y-scale subquestions
4) Add the following script to the source of the array question. Replace "QQ" with the array question ID.
As stated in the referenced forum post,
the replacement text in the dropdowns will not be stored in the data - you will need to map to it in post-survey analysis.
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$('#questionQQ .answer_cell_001 option[value=1]').text('No recurro');
$('#questionQQ .answer_cell_001 option[value=2]').text('Arocena Gustavo');
$('#questionQQ .answer_cell_001 option[value=3]').text('Aspra Manuel');
$('#questionQQ .answer_cell_001 option[value=4]').text('Bravo Ricardo');
$('#questionQQ .answer_cell_001 option[value=5]').text('Zalazar Martin');
$('#questionQQ .answer_cell_002 option[value=1]').text('No recurro');
$('#questionQQ .answer_cell_002 option[value=2]').text('Bravo Ricardo');
$('#questionQQ .answer_cell_002 option[value=3]').text('Fernandez Flavio');
$('#questionQQ .answer_cell_002 option[value=4]').text('Zalazar Martin');
$('#questionQQ .answer_cell_002 option[value=5]').text('').hide();
});
</script>
