Assuming you mean electrically, Copper is roughly 10 times less electrically-resistant than steel. That is probably the best measurement to gauge by for what you are asking.
I would think heat conveys much like electricity, the greater the number of "free' electrons the less resistance to the heat , therefore copper would be faster then the other three choices.
Superconductors are materials that offer no electrical resistance whatsoever but the highest temperature any known superconductor can be while retaining its conductive properties is -181 degrees Celsius, making them an extremely impractical and expensive material for most purposes. As far as I know the most conductive material at room temperature is pure silver, which is slightly more conductive then pure copper and 50% more conductive then pure gold. Copper and gold are both used commonly for conduction however because copper is much cheaper then silver and nearly as conductive, and gold is more resistant to corrosion then either silver or copper despite its reduced capacity for electrical conduction.
Using copper washers as opposed to using aluminum aren't to much more beneficial except for the fact that copper is more reusable. On the down side copper is more expensive.
SO they don't melt on the stove. Also they are durable, good conductors of heat. Copper pans are much more expensive, and so are cast iron ones.
If the steel contains by weight one or more of the following elements in the proportion shown, it is an alloy steel. 0.3 % or more of aluminium 0.0008 % or more of boron 0.3 % or more of cobalt 0.4 % or more of copper 0.4 % or more of lead 1.65 % or more of manganese 0.08 % or more of molybdenum 0.3% or more of nickel 0.06 % or more of niobium 0.6 % or more of silicon 0.05% or more of titanium 0.3 % or more of tungsten (wolfram) 0.05 % or more of zirconium 0.1 % or more of other elements (except sulphur, phosphorus, carbon and nitrogen), taken separately. Any steel not containing one or more of the above elements in the weight proportions shown, is a non-alloy steel.
Copper is amongst the most thermally conductive material on the market. In most cases, copper is too hot for most cooking purposes, which is why aluminum and stainless steel are more popular.
It is much like electroplating. To make something more conductive it is given a coating or cladding of another more conductive element. Take copper clad ground rods. The original ground rod is just a steel rod. To make is more conductive a coating of copper is plated to it. This now enhances the steel ground rod buy improving its conductivity with the soil around it and secondly giving it an anti rust covering that will last the life of the ground rod.

Copper is a much better conductor of heat than steel. This is why stainless steel cookware is clad in copper; it gets the heat in more effectively. Regarding a copper pot compared to a steel pot - I don't think anyone makes solid copper cookware. It leave a strange metallic taste in the mouth.
The layers at the bottom of stainless steel cookware provides better heat conduction (heat spread evenly) and durability. Aluminium-base takes longer time to heat up but retains cooking temperature longer while copper-base is quickly in heating up and cooling down.

Carbon Steel is much stronger metal.
Yes...all metals are will conduct electricity.
Only at low temperatures, at higher temperatures copper wouldn't be a better heat conductor than steel. The spring force is much tighter in the steel because its melting point is much higher, but at low temperatures its because it models something, like a rollercoaster, but no. Also Copper is more magnetic with its audience, which is the way. To test this out get some boiling water in a beaker and attach thermometer to the copper and steel and see which one heats up first.
