Yes, some can work in other panels. But you go to an electrical supplier and get the one
that is the brand of the panel. If it is old and you can't find it, then try a GE breaker.
No, the Square D designed breaker can only be installed in a Square D manufactured panel.
The Cutler Hammer BR series will fit and also the Connecticut Electric UBITBC series will fit your Westinghouse service panel.
You need a breaker rated for 10 amps and 250 volts. The breaker must also fit properly in your panel.
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.
In the United States, if the wire is #8 copper or larger (smaller number) it will work fine on a 40 amp breaker. If the wire is #10 copper, there is something wrong with the breaker if it does not fit. Pull the breaker out of the panel and look into where the wire terminates to see why the #10 wire won't fit.
The panel and breaker have to be of the same manufacturer. This way the breaker will fit into the panel. If the panel has a push in bus bar, the breaker must also be the type to accept the bus bar. If the bus bars in the panel are of the bolt in type then the breaker also has to be a bolt in breaker.
No, a Cutler Hammer will not work in a GE panel or vice versa.

No, they will not fit. You can use Westinghouse, Cutler Hammer BR series, and Connecticut Electrical UBITBC series breaker. All of those will fit.
Yes, the code requires a complete dead front so that no access can be made to the bare distribution bus behind the panel face.

No, if you have a Square D distribution panel only Square D breakers will fit in it.

There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
