Your error is here.

Ye I knew and i have already killed process for that port . Also rebooted my server but still it bench not started.

Are you using production or development ?

try sudo supervisor-ctl stop all

I am using development environment. Bench start is only working with development environment.

Supervisor process is only working with production environment.

Then try and kill redis process and again try.
