I would use 4 AWG copper to be safe.
None! Distribution panel designed to use specific type of circuit breakers. It's a NEC violation to install different type of breaker even it fits perfectly.
Your circuit box should have a label on the door listing compatable breakers. For instance, my American Switch 200 amp panel lists what American Switch breakers are usable on that particular panel, and then it goes on to list other manufacturers whose breakers will work in the panel. Mine can use Frank Adam Type A, FA-D, QP & QPH, Bryant Type BR-D and BD breakers as well as Westinghouse Type QP and Q. I am not sure that I would go with the adage that if it fits use it. Check your Panel Box for the tag listing compatible breakers.
In my experience, NOTHING is compatible with a Murray panel. Others claim there are certain Siemens and Federal Pacific breakers or Eaton type "CL", but you might have to obtain permission from the inspector to use anything other than Murray.

The electrical terminology for this type of breaker is a tandem breaker. It is where two breakers circuits can be in the same one breaker slot in a distribution panel. On this type of breaker there will be two output for a circuit value of what ever the breaker is rated for.
Without knowing the brand name of the distribution panel it is hard to tell what type of breakers that you are looking for. If there is an electrical wholesaler near your location, take the sample into them for identification. They will probably be able to help you.
To be short...Yes
Any electrical supplier should be able to get that for you. Check you local Yellow Pages for electrical suppliers. <<>> A GDP 200 is an older type breaker that was manufactured by General Switch. It had a 10KAIC (interruption capacity). This type of distribution panel was used 40 to 50 years ago. The main breaker is almost next to non existent. The main breakers were manufactured by a different company and General Switch used them in their panels. You might look on EBay under electrical breakers. The original branch circuit breakers are also hard to find but some different brands will fit. There are some sites on the net that refurbish old breakers for your type of scenario. Safety wise it is not a good idea to mix and match breakers. You might want to consider budgeting for a distribution panel change.
In home installations, the breakers will be found in the service distribution panel. In some homes this distribution is found in the basement. In ranch type homes, slab on grade, the distribution panel will be found in the utility room that houses the washer and dryer.
Type AE and AQ accept bolt-on breakers, type AL accepts plug-in breakers.
Pinning breakers is becoming a thing of the past. This is due to the manufacturing of two pole breakers with one common trip reset handle. The electrical code states that on a 240 volt breaker if one leg trips the other leg must be disconnected from the supply also. This is a safety factor so that if they weren't tied together and one leg tripped the other half of the breaker would remain "hot". Any one working on that circuit in the tripped position could get a nasty shock from the un-tripped leg. Pinning the breakers on 240 volts was done because it was convenient to use single pole breakers in the distribution panel. To abide by the code the two single pole breakers were common tied together. When the branch circuits share a neutral to a common box they have to be common tied for the same reason above. This type of circuit is found on kitchen counter receptacles. Two separate circuits that share a neutral and go to separate junction boxes do not need the breakers tied.
The home type used to be a little less expensive, and they do not have the little red flag when the breaker trips, The qo has the little red flag, which is eaiser to see, which breaker is tripped when you open the panel door the little red flag you can see where with the home style you look for the breaker that is not completly on. To me it was a step backwards with the introduction of the home style breaker we have installed both panels and Q O I prefer. And the breakers are not interchanable from panel to panel
