Answer 1

Here i want to share how i got discount problem fixed. Discounts are in adjustment per order_item in order object. So i got discounted amount by below:

$adjusment_order_item = $order_item->getAdjustments();
            if($adjusment_order_item){
              $adjustment_data = $adjusment_order_item[0]->getAmount();
              $adjustment = $adjustment + $adjustment_data->getNumber();
              $adjustment_currency = $adjustment_data->getCurrencyCode();
            }
