I have solved this with added following codes in AdminOrdersController.php
Added
CONCAT(ad.`firstname`, \' \', ad.`lastname`) AS `shipping_customer_full_name`,
ad.phone_mobile as shipping_phone_mobile,
this 2 line after line 65
And added
LEFT JOIN `'._DB_PREFIX_.'address` as ad ON id_address_delivery= ad.id_address
after line 76
NOW i can see Delivery person name & phone number on order list
SOLVED!
