Can somebody please tell me how to use Turretbots? I know we need another device to run the client on for it. Is it possible to run Turretbot in parallel space app (parallel space VO and original vo can run at same time, so I got 2 clients).

Second client can enter a turret and use it like any other player. Most people run a Gunner bot on a second device like a Android so it easy to aim it. Other than that you could make a plugin do some simple stuff via chat command
