How to receive all the meta information of a post ?

I’m not sure that this is what you wanted, but let me try…

<?php
    $titles = get_post_meta( $post->ID, 'title' );
    $urls = get_post_meta( $post->ID, 'title' );
?>
<table>
    <thead>
        <tr>
            <th>Title</th>
            <th>Download URL</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ( $titles as $k => $title ) : ?>
        <tr>
            <td><?php echo esc_html($title); ?></td>
            <td><?php echo esc_html( array_key_exists( $k, $urls ) ? $urls[$k] : '' ); ?></td>
        </tr>
    </tbody>
</table>
