Your question raises some questions within your question:

1: Yes most jet engines have TR's (thrust reversers) that are designed when deployed to change the direction of trust from aft to forward... thus creating the opportunity to reverse the direction of the aircraft, however.. they would not be used in this fasion... there is ground support equipment (GSE) for this purpose... but it is used to reduce the speed of the aircraft upon a landing. I am sure you have seen this while on board an airliner. But the question would be, Why would you want (or need) to use your thrust reversers in this fashion?

2: Prop equipped aircraft do have the ability to change the pitch of the prop, and thus changing the direction of the trust... same principle as before. Again it is possible to move the aircraft in reverse... however aircraft usually are not equiped with aft facing mirrors.. .so know what is behind you at all times is rather tough. For this I would say is not a good practice, and again relying on GSE would be a better directed effort.

I hope this helps and gives you a basis of understanding aviation.

Airplanes do not have a drive train like an automobile. If that is your question, then the answer is no. Are they capable of taxiing backwards? Yes, although it's not very safe to do so without ground handlers, so it's not common. Turboprops can reverse the propellers and slow down without much wheel braking. Jets can redirect the air forward by blocking the exhaust and once the "reversers" are "deployed" thrust can be added for additional slowing. Commercial airliners get pushed backwards from the gate by a tug, and then engines can be started. Light airplanes can be pushed backwards by hand.

Not in flight, only airplanes with VTOL capabilities can go reverse in the air(Harrier, Osprey, Yak-141, BA-609).
Not all airplanes have reverse, but some have.
They can go backward only on ground.
All airplanes that have thrust inversion (jet airliners, variable-pitch propeller airplanes, but also Panavia Tornado and SAAB Viggen) can go reverse on ground.
The link below is a video showing a Viggen in reverse and turning.

Most jet and turboprop aircraft have reverse thrusters or can reverse the pitch of propellers to slow down after landing.

Some jet aircraft and many turboprop can go in reverse, or back up, on the ground. Aircraft such as the C-130 Herc are particularly adept and reversing the pitch of the props, back up, and even back into a "parking stall".

Helicopters and the V-22 Osprey can fly backwards in the air.

Jet aircraft do. When you watch them land or you're onboard and you hear that roar that is both the flaps and the reverse thrusters because the brakes and flaps onboard while effective on there own cannot fully stop a huge jet aircraft. If you also look on a DC-9 for Northwest the pilots back away from the gate without a tow.

Short answer: Most jet and turboprops have reverser mainly to slow the plane down. Jet by redirecting the thrust and on TP to change the blade angle. However, TR should not be used to back up - when u hit the brakes backing up you risk a tail strike - the tail end up hitting the ground if it is a tricycle gear. That's why we have GSE for push back. Hope that helps.

yeah but the thing that you are asking is maybe the reverse thrust of an Aircraft wherein the Pilot wikll execute this if the plane has touched down the runway. one Obvious sign is when you hear the plane roaring noisily. this roaring noise is only temporary since the pilot of the airplane will then move the throttle into idle position again when it reaches the speed of 60KIAS.

They certainly do. Some propeller planes have reversible pitch propellors, it is not really meant for reversing but to slow the plane when landing. It could in fact move it in reverse.
Jet planes have a system that closes off the engine outlet that reverses the thrust, thus slowing it when landing. Same principle as ptop plane.

Yes, most jet aircraft have reverse thrust. Most however are not authorized for reverse taxi. Reverse thrust is mainly used to slow on landing to about 60 knots where it is then worthless.

Yeah, of course! On a large airliner, the pilots use reverse-thrust HARD, on the propellers, for several seconds every time they land, to slow it down. It's a nauseating experience for some people. They only engage the wheel brakes after they get it down to below approx. 60 MPH,. The thing is still whipping along at about 140 when the wheels first make contact.
