Answer 1

Create associative array like below.

public function getAllItems()
{
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $order = $objectManager->create('Magento\Sales\Model\Order')->loadByIncrementId(000000014);
    $orderItems = $order->getAllItems();
    $itemQty = array();
    foreach ($orderItems as $item) {
        $itemQty[]=array('quantity'=>$item->getQtyOrdered(),'description'=>$item->getDescription(),'name'=>$item->getName(),'price'=>$item->getPrice());

    }
    return $itemQty;
}

I think you need an index in the array. Try this

public function getAllItems()
{
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $order = $objectManager->create('Magento\Sales\Model\Order')->loadByIncrementId(000000014);
    $orderItems = $order->getAllItems();
    $itemQty = array();
    $i = 0;
    foreach ($orderItems as $item) {
         $itemQty[$i]['quantity'] = $item->getQtyOrdered();
         $itemQty[$i]['description'] = $item->getDescription();
         $itemQty[$i]['name'] = $item->getName();
         $itemQty[$i]['price'] = $item->getPrice();
         $i++;
    }
    return $itemQty;
}
