Does it show total data in or out per flow timeout?

like i configured  cache timeout active 60(sec) under flow exporter NetFlow-Exporter.

so does it show total data in or out per 60 seconds?

can we see currently how much bandwidth is being used in download or upload in NetFlow?

Hello.

The information is current value in netflow cache. It means - that is the number of bytes since the entry was created.

No good way to calculate bandwidth with Netflow only (unless you accept measurement error of 20+%), you may use interface statistics or ingress/egress QoS counters instead.
