The first thing is that when updating fields that do not always have values then you need to use the field key. This is covered in the documentation.

I would set the entire group using update_field()

$value = array(
  // a group field's value is an array
  // sub field key => value pairs
  // this is a simple sub field
  'field_xxxxx' => 'value',
  // a nested group would be a nested array
  'field_yyyyy' => array(
     // nested group field
     'field_zzzzz' => 'value of field',
  )
);
update_field('field_ggggg', $value, 'options');
