}

Answer 1

$model = Mage::getModel('marketplace/sellerprofile')->load($fieldId); // you current seller id

echo $model->getIncludeInOthersellers(); // this will give you desired 

in renderer add this code for getting values

public function OtherSellerList(Varien_Object $row)
    {
        $id = $row->getId();
       $otherseller = Mage::getModel('marketplace/sellerprofile')->getCollection();
$otherseller->setPageSize(5)
        ;
$otherseller->getSelect()->order(new Zend_Db_Expr('RAND()'));
  $sellerid=array();
   foreach($otherseller as $seller)
    {
    $sellerid[]=$seller->getId();
     }

return implode(',',$sellerid);



    }

Answer 2

You need to sort collection using seller id in descending order like below

$model = Mage::getModel('marketplace/sellerprofile')->getCollection()->setOrder('seller_id', 'desc'); 
$model->getSelect()->limit(5);
