I’m not sure but in my case this coding is valid for me.

Here is a code from WordPress Reference.
http://codex.wordpress.org/Function_Reference/fetch_feed

<h2><?php _e('Recent news from Some-Other Blog:'); ?></h2>
<?php // Get RSS Feed(s)
include_once(ABSPATH . WPINC . '/feed.php');

// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed('http://example.com/rss/feed/goes/here');
if (!is_wp_error( $rss ) ) : // Checks that the object is created correctly
    // Figure out how many total items there are, but limit it to 5.
    $maxitems = $rss->get_item_quantity(5); 

    // Build an array of all the items, starting with element 0 (first element).
    $rss_items = $rss->get_items(0, $maxitems);
endif;
?>

<ul>
    <?php if ($maxitems == 0) echo '<li>No items.</li>';
    else
    // Loop through each feed item and display each item as a hyperlink.
    foreach ( $rss_items as $item ) : ?>
    <li>
        <a href='<?php echo esc_url( $item->get_permalink() ); ?>'
        title='<?php echo 'Posted '.$item->get_date('j F Y | g:i a'); ?>'>
        <?php echo esc_html( $item->get_title() ); ?></a>
    </li>
    <?php endforeach; ?>
</ul>

If you change all”$rss” to “$rssA“,”rssB” or other unique word,you could display more than 2 columns in the same page.
Remind that you should change “$rss_items” to “$rssA_items“,”rssB_items” also.

Here is the full code that has been changed.

<h2><?php _e('Recent news from Some-Other Blog:'); ?></h2>
<?php // Get RSS Feed(s)
include_once(ABSPATH . WPINC . '/feed.php');

// Get a SimplePie feed object from the specified feed source.
$rssA = fetch_feed('http://example.com/rss/feed/goes/here');
if (!is_wp_error( $rssA ) ) : // Checks that the object is created correctly
    // Figure out how many total items there are, but limit it to 5.
    $maxitems = $rssA->get_item_quantity(5); 

    // Build an array of all the items, starting with element 0 (first element).
    $rssA_items = $rssA->get_items(0, $maxitems);
endif;
?>

<ul>
    <?php if ($maxitems == 0) echo '<li>No items.</li>';
    else
    // Loop through each feed item and display each item as a hyperlink.
    foreach ( $rssA_items as $item ) : ?>
    <li>
        <a href='<?php echo esc_url( $item->get_permalink() ); ?>'
        title='<?php echo 'Posted '.$item->get_date('j F Y | g:i a'); ?>'>
        <?php echo esc_html( $item->get_title() ); ?></a>
    </li>
    <?php endforeach; ?>
</ul>

Again, I’m not sure because I’m not professional of coding, but it works well for me.
