$rand will be an array of keys from $images..

I guess you should rewrite your code to something like this:

<?php 
$images = get_field('khach_hang', 'option');
if( $images ):
$rand_keys = array_rand($images, 10);
foreach( $rand_keys as $key ): ?>
    <img class="khac_hang_item" src="<?php echo $images[$key]['url']; ?>" alt="<?php echo $images[$key]['alt']; ?>" />
<?php  endforeach; ?>
<?php endif; ?>

you should loop $rand_keys instead of $images...
