I think you can achieve in this way but you can also try easy solution
<?php
$_helper = $this->helper('catalog/output');
$_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('*')
->setVisibility(array(2,3,4))
->setOrder('created_at', 'desc')
->setPageSize(10);
$count = $_productCollection->count();
?>
<div class="item active">
<?php
$i=0;
$flag=false;
foreach($_productCollection as $product)
{
if($i<5)
{
?>
<div class="lpitem">product <?php echo $i;?></div>
<?php $i++;
?>
<?php
}
else
{
if($i==5)
{
$flag=true;
?>
</div>
<div class="item">
<?php
}?>
<div class="lpitem">product <?php echo $i;?></div>
<?php $i++;
?>
<?php }
}
?>
</div>
Let me know if its works for you or not
