Not sure on top and middle, but the bottom one is the intake air temperature sensor. It should screw into an intake runner on the driver side of the lower intake.
For clarification what are you calling the left side? On a vehicle, the left side is viewed with you standing behind the vehicle facing forward. In the US, the driver sits on the left side.
A 302 has a knock sensor at the the back of the intake manifold.
The middle and bottom picture look like the same sensor to me. Are they two views of the same part? Your hand is blocking our view of where the IAT us screwed into the intake manifold. Is there another sensor there or an open hole?
Yes the first picture is on the passenger side it's a two pin connector close to the firewall the second picture is the driver side I picked up the sensor out of some leaves close to the fuel rail on the driver side
