Thanks to @Autista_z, the working code:

    <?php 

    $args = array(
     'cat' => 140, // Category ID
     'posts_per_page' => 10
     );
     $modone_qry = new WP_Query( $args );
    ?>

    <?php $post_number = 0; ?>

    <?php if ( $modone_qry->have_posts() ) : while ( $modone_qry->have_posts() ) : $modone_qry->the_post(); ?>

    <?php $post_number++; ?>

    <?php if ($post_number === 1): ?>

        <h1><?php the_title(); ?> BIG</h1>

    <?php else: ?>

        <h1><?php the_title(); ?> SMALL</h1>

    <?php endif; ?>

    <?php endwhile; else : ?>
        <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
    <?php endif; ?>

</div>

I dont know wordpress, but with simple php you can do it like this

<?php 

$args = array(
 'cat' => 140, // Category ID
 'posts_per_page' => 10
 );
 $modone_qry = new WP_Query( $args );
?>

<?php $post_number = 0; ?>

<?php if ( $modone_qry->have_posts() ) : while ( $modone_qry->have_posts() ) : $modone_qry->the_post(); ?>

<?php $post_number++; ?>

<?php if ($post_number === 1): ?>

    <!-- HTML of latest post - First in loop -->

<?php else: ?>

    <!-- HTML of others posts -->

<?php endif; ?>

<?php endwhile; else : ?>
    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>
