can you install dishwasher/disposal without air gap ?

You CAN, but it is not a good idea.

Yes, but the drain water may back up in the sink if it is connected to a garbage disposal rather than the sink drain..

Although it can be done safely if done right often local codes are requiring an air gap.

You risk back siphonage from the dishwasher. Check the installation recommendations for your particular machine, but it is generally easy enough to overcome.

Sure. Disposals install directly into the drain line, they're part of it. You still need a P-trap downstream of it but that's all.
Dishwashers usually dump directly into the tailpiece of a sink's drain lines. It isn't an air gap per se, but an air break - similar in function but different in construction.
