No not all do. It depends on how the wheel was designed. Some use old fashion hub caps.
You will need to wither visit a repair shop for an accurate measurment or contact the manufacturer of the wheel
you can engage the 4 wheel drive with the vehicle in neutral, then make sure you lock the hubs manually on the wheels. turn the dial on the hub caps of the front wheels to lock, when not in 4 wheel the wheels need to be in free mode.
Try using the lug wrench. If the car has wire wheel caps, you will need an adapter tool to pry off the center caps and unscrew the cap from the wheel
Try using the lug wrench. If its an older model with the wire-wheel caps, you'll need an adapter tool to unscrew the caps from the center after you've removed the center cap.
The only reason you would need new wheel center (hub) caps is if they are not visually appealing enough to you. they provide little or nor function to the car except aesthetics. Though, if any caps are loose or are cracked or broken, they should be replaced or simply removed so that they do not come off the car during driving and cause an accident with the person behind you.
Only if your towing the vehicle by the rear wheels. If you are towing by the front wheels you do not need to unlock the steering wheel.
a wrench
Jack the car up on the side the wheel is on, grab the L shaped spanner thing, undo the nuts (4 of them) take the wheel off. Make sure to jam things against the ground wheels so the car doesn't roll. If you have hub-caps, they should just pull off. Cheap ones may break. If the hub-caps have bolts on them, then you have to take the wheel off first. Otherwise you need to take the hub-caps off first.
The bolt pattern is only one part of proper wheel fitment. If you are using wheels from a different model car, you also need to be aware of wheel offset and center bore. You should use wheels of similar width and offset so they don't stick out or sit too far in which can cause clearance issues. The center bore needs to be large enough to fit over the hubs on your car. Most cars come with hub-centric wheels to fit exactly on the hub flange, if you use a wheel with larger bore you can get hub rings to center the wheel. On some vehicles you may get excessive vibration by using wheels without the hub rings or the proper hub bore.
