On Purchase orders list I am unable to differentiate between the POs with received good (Received) and POs with pending and goods still to receive (Outstanding).

There is no such bult-in capability. Purchase Orders tab only allows you to generate a document to send to a supplier. Purchase orders have no financial impact and are not tracked by the program in any way. But when you receive an invoice, you can copy them to a purchase invoice for convenience.
If you want to know status, create a dropdown custom field with status options and set it to show as a column.
