The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
If the breaker will snap on the bus bar, yes.
Use of a double pole breaker or a single pole breaker depends entirely on the application. If you don't know about the application, contact a qualified electrician in your area.
A single phase circuit uses a 2 pole breaker if the circuit is 120/240 split phase and the load is connected 240. Both legs are hot, so both need to be protected. This is the normal US/Canada configuration.

6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
AWG 12/2 requires the use of a 20 amp single pole breaker.
If the breaker will snap on the bus bar, yes.

Probably
In America, a 2-pole breaker is controlling 240V. 120V per leg.

Yes.
If your breaker box will accept tandom breakers you can remove 4 single pole breakers add 2 tandoms this will empty 2 spaces for your 2 pole 30 amp for the dryer
