add in the end of modules/News_Management/func.php

function insert_news_get_num($lngcode) { return array_slice(func_news_get($lngcode), 0, 3);}

then in skin1/customer/news.tpl change

{if $is_news_exist}

    {capture name=menu}

      <div class="news item">
        {include file="today_news.tpl"}
      </div>

to

{if $is_news_exist}

    {capture name=menu}

     {if $news_message eq ""}
       <div class="news item">{$lng.txt_no_news_available}</div>
     {else}

       {insert name="gate" func="news_get_num" assign="all_news"   lngcode=$shop_language}
       {section name=newsloop loop=$all_news}
         <div class="news item">
          <strong>           {$all_news[newsloop].date|date_format:$config.Appearance.date_format}</strong><br />
  {$all_news[newsloop].body}<br />
      </div>
        {/section}
        <br />
       {if $usertype eq "C"}
        <a href="news.php" class="small-link prev-news">{$lng.lbl_previous_news}</a>
        {/if}
       {/if}

This should work, though I didn't tested it.
