just to understand:

• you had a flexible field with 15 layouts.
• at page/article/cp you show that flexible field.
• you/user can now select one or more of this flexible fields.

and all that you wish is, when you didnt select/add the neck: you dont want to show neck?

that is what flexible field normally does. (add optional content-blocks, and show them only if needed. with that you can have required fields like a keyvisual a with title, but only when you add keyvisual-block)

what it does not do is: to look if a layout is already choosen 1 or more times, and if not display a alternate content.
if you really need that you need to set a variable inside the get_row_layout loop. also you had to put the values into a variable first. after all layout you check each variable and check if it is filled or not & set alternates

try if you can adapt this code

<?php
//define variables 
$head= '';
$shoulder ='';
$neck ='';
//check for layouts and the values inside
if( have_rows('attach_files_multiple') ): while ( have_rows('attach_files_multiple') ) : the_row(); 

if( get_row_layout() == 'neck' ) : 
$neck .= 'all about neck';
endif;
if( get_row_layout() == 'shoulder' ) : 
$shoulder .= 'all about shoulder';
endif;
if( get_row_layout() == 'head' ) : 
$head .= 'all about head';
endif;

endwhile; endif;

//check for filled values and build layout or the alternates
if ($head) {
echo $head;
} else {
echo 'no head was chosen ';
}
if ($shoulder) {
echo $shoulder;
} else {
echo 'no shoulder was chosen ';
}
if ($neck) {
echo $neck;
} else {
echo 'no neck was chosen ';
}
 ?>

why do you work with flexible fields when you replace anyway everything not filled with a default value?
