Could you help me how can we use the dynamics energy of a high speed low pressure (atm) air, exits from a piping system equipped with a fan, without increasing the pressure on the exitting air and accordingly on the fan.

I think if it was water instead of the air, we could simply do it by installing a water turbine next to th exitting water without increasing the pressure, ( let the water exit in the atmosphere pressure and by using its velocity it is going to the turbine and will give us energy)

But I think in turbines, there is no pressure lost and just kinetic energy lost because high speed atmospheric pressure water come in and low speed atmospheric pressure water come out.

Its a thermodynamics problem.
i can't really recall the equations off the top of my head but the ammount of power recovered is the difference in enthalpy from the beginning of the turbine to the other side of the turbine, a combination of speed and temperature.

You cannot have air or water flow without pressure of some sort.
You will definitely need to have pressure to drive the air or water thru your turbine.
If you want the turbine to rotate, you will require even more pressure.

You can't. Anything that you put in the flow that extracts power will also increase the pressure.
