Does it mean that even in the air we are travelling at the same speed of the vehicle?

Well on the classical physics point of view you would fall back to the same place in a moving vehicle after jumping - this is because when you jump you have the vertical velocity added to the horizontal velocity of the vehicle so that when you land you will have travelled horizontally the same distance as the moving vehicle.
However, consider this! Think of a flag pole several miles tall at the earth's equator. Drop an apple from the top. Will it fall exactly to the bottom? NO IT WONT.
This is because the horizontal velocity imparted to the apple at the instant of letting go is faster than the speed of rotation at the bottom of the pole. This is because effectively the top of the flagpole travels faster than the bottom.
With this in mind (and taking into consideration Coriolis forces - the ones that cause anti-cyclones to rotate) you will not actually fall to exactly the same spot when jumping in a moving vehicle.
Clear?

This is another relativity question. If you are in a bus travelling at 50mph you are also travelling at 50mph in relation to that which is not in the vehicle with you. Though you are stationary in relation to the floor of the vehicle. If the vehicle stopped suddenly by running into a concrete block, such as a bridge support, you would if you were standing be propelled at 50mph toward the front of the vehicle, (really the bus would have stopped moving, but you would still be in motion due to momentum). If all the windows are closed the air inside the bus is just the same as you, but if a window is opened you will get air exchange, sometimes very rapidly.

While inside the vehicle you are travelling at the same speed.Why not try jumping with the aid of a trampoline say ten feet into the air from the back of a moving truck and see where you land?

Imagine what's happening from outside the vehicle, as if it were made of glass. You would see that although you are simply jumping up and down again in relation to the vehicle, in fact because the vehicle is moving forwards, you are actually jumping in an arc, as if you yourself were running and jumping. If that didn't happen, as soon as your feet left the floor, the back of the vehicle would come up and smack you! Which wouldn't be nice!

You do move Dah. If you didn't move you would stay still and the car would crash into you. You are moving at the same velocity as the vehicle, so you will land on approximately the same spot give or take loss of velocity due to friction etc etc, So yes you are moving at the same speed as the car just on take off.

Yes you are moving at the same speed as the vehicle.
However only an outside observer would 'see' the speed relatively. In other words he can see the speed from the perspective of someone standing still and observing it move from point a to point b within his time frame.
You however can not observe this speed as you are unable to stand still and observe it yourself (as you are in the vehicle or plane)
In this way time is relative to the observer.

It is Newton's first law. You are already moving with the car and will continue to do so even if you are not touching it at the moment, unless something pushes you. That something could be air, if for example you were in the open air bed of a pickup and jumped the wind might blow you back some.

Because you inherit the velocity of the vehicle, it is your frame of reference when you are moving. Yes, you are basically traveling at the speed of the vehicle when you are airborne in that situation.

Newton's 1st law: an object in motion tends to stay in motion unless acted on by an outside force. Your body is in motion and wants to continue going in the same direction at the same speed. Therefore your body will land in the same place unless something makes it land elsewhere.

No, I in no way do this. I survive a planet that rotates at very almost 1667 kilometers according to hour and which has an orbital speed of roughly 107,000 kilometers according to hour... so i'm surprisingly lots continuously on the flow.
