How to randomized the post once in a day

Hello guys i have got a code from stackexchange which is working somehow but giving one issue that the post repeating themself and no. of post per page is not working here is the code where i called the template

<?php
/**
 * Loop - Archive
 *
 * This is the loop logic used on all archive screens.
 *
 * To override this loop in a particular archive type (in all categories, for example), 
 * duplicate the `archive.php` file and rename the duplicate to `category.php`.
 * In the code of `category.php`, change `get_template_part( 'loop', 'archive' );` to 
 * `get_template_part( 'loop', 'category' );` and save the file.
 *
 * Create a duplicate of this file and rename it to `loop-category.php`.
 * Make any changes to this new file and they will be reflected on all your category screens.
 *
 * @package WooFramework
 * @subpackage Template

 global $more; $more = 0;

woo_loop_before();
if (have_posts()) { $count = 0;

    $title_before = '<h1 class="archive_header">';
    $title_after = '</h1>';

    woo_archive_title( $title_before, $title_after );

    // Display the description for this archive, if it's available.
    woo_archive_description();
?>

<div class="fix"></div>
<ul id="archivelist">

<?php
    while (have_posts()) { the_post(); $count++;

        if(is_post_type_archive('styleword')) {get_template_part( 'content', 'stylewordall' );} else{woo_get_template_part( 'content', get_post_type() );}

    } // End WHILE Loop
} else {
    get_template_part( 'content', 'noposts' );
} // End IF Statement

woo_loop_after();?>
</ul>
<?php
woo_pagenav();
?>

and here is the code i used to call specific post types that is styleword and here is the code for it

<?php if ( false === ( $custom_query = get_transient( 'random_styleword' ) ) ) {
  // It wasn't there, so regenerate the data and save the transient

   $args = array(
    'posts_per_page' => 5,
    'post_type'  => 'styleword',
    'orderby'=> rand
);

  $custom_query = get_posts( $args );

  //Now we store the array for one day.
  //Just change the last parameter for another timespan in seconds.
  set_transient( 'random_styleword', $custom_query, DAY_IN_SECONDS );
} 


foreach ( $custom_query as $post ) : setup_postdata( $post );
 echo count($custom_query); ?>

<li><article <?php post_class(); ?>><div class="image-quote-wrapper">
<?php

$imagequote = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full' );
$imagequoteurl = $imagequote['0'];


    echo '<img src="'. $imagequoteurl .'" width="320px" class="nopin"/>';

?>
