if ($sellerProductInfo->getSize() == 0) {
$rowsocial= Mage::getModel('marketplace/userprofile')->getPartnerProfileById($productowner['userid']);

 }
}

but i am getting error : Fatal error: Call to a member function getSize() on a non-object in line : if ($sellerProductInfo->getSize() == 0)

This means your $sellerProductInfo is not an object and you are calling the function getSize() in non-object.

I am not sure what $this->getSellerProductInfo($productowner['userid']) function does, but to get rid of your error you can add this condition:

$sellerProductInfo = $this->getSellerProductInfo($productowner['userid']);

if($sellerProductInfo){ //check if this returns true
  if ($sellerProductInfo->getSize() == 0) {
  $rowsocial= Mage::getModel('marketplace/userprofile')->getPartnerProfileById($productowner['userid']);
  } else {
   $sellersProductInfo = $this->getSellerProductInfo();
   if ($sellersProductInfo->getSize() > 0) {
     $sellerId = $sellersProductInfo->getFirstItem()->getSellerId();
     $rowsocial = Mage::getModel('marketplace/userprofile')->getPartnerProfileById($sellerId);
   }
  }
}

Remember

Your above script will never get called if $this->getSellerProductInfo($productowner['userid']) doesn't return anything.

Magento – Fatal error: Call to a member function on non-object

The problem is in the config.xml file in the declaration of the model alias.
In your case is:

<models>
    <meteorify_observerexample>
        <class>Observerexample_Model</class>
    </meteorify_observerexample>
</models>

But it should be

<models>
    <meteorify_observerexample>
        <class>Meteorify_Observerexample_Model</class>
    </meteorify_observerexample>
</models>

Magento 1.x Fatal Error – Call to a Member Function getData() on a Non-Object

You are using the event incorrectly.

In event checkout_onepage_controller_success_action

the order is not sent as an object, but as the order id. (as order_ids)

Mage::dispatchEvent('checkout_onepage_controller_success_action', array('order_ids' => array($lastOrderId)));

(ref Mage_Checkout_OnepageController::successAction)

Thus in your observer you need to get the id, as such:

$orderIds = $observer->getEvent()->getOrderIds(); // returns an array 
$orderId = array_shift($orderIds);

and instantiate the order object using

$order = mage::getModel('sales/order')->load($orderId);

(the above written off the top of my head, but the jest of it should be correct)
