Answer 1

Use this below code. It maybe helpful for you :

$orderDatamodel = $objectManager->get('Magento\Sales\Model\Order')->getCollection();
$orderDatamodel->getSelect()->limit(5);
    foreach ($orderDatamodel as $key => $value) {
        $order = $objectManager->create('\Magento\Sales\Model\Order')->load($value->getId());
        $orderItems = $order->getAllItems();
        foreach ($orderItems as $item) {
            $product_name = $item->getName();
            $product_id = $item->getProductId();
            echo $product_name . "--" . $product_id;
        }
    }

Answer 2

In below code orders has been set in descending order and setPageSize() will give you 5 records only.

$ordercollection = $objectManager->get('Magento\Sales\Model\Order')->getCollection();
$ordercollection->setOrder(
    'created_at',
    'desc'
)
    ->setPageSize(5)
    ->setCurPage(1);

foreach($ordercollection as $order){
    echo $order->getRealOrderId();

    //To get order items
    $items = $order->getAllItems();
    foreach ($items as $item) {
        echo $item->getPrice();
        echo $item->getSku();
    }
}

Notes:

• Don't use Object Manager.
• Inject OrderRepository or Interface Class
