But how to do only validate-alpha-with-spaces ?

Answer 1

Reference: Magento validation class

You can create you own custom validation class

<script type="text/javascript">
var theForm = new VarienForm('theForm', true);
Validation.add('validate-alpha-spac','You failed to enter baz!',function(v)        {
    return Validation.get('IsEmpty').test(v) ||  /^[a-zA-Z0-9 ]+$/.test(v)
});  
</script>

or

  Validation.addAllThese([
      'validate-alpha-space', 
      'Please use letters only (a-z or A-Z) in this field.', 
      function (v) { return Validation.get('IsEmpty').test(v) ||  /^[a-zA-Z0-9 ]+$/.test(v)
 }]),
