The cup.
Dark objects will absorb more sunlight, converting it into heat energy, which is then passed on to the water - thus making it heat faster.
yes
starting from absolute zero, even twice as much water as the tea would contain more heat. Even starting at 0 Celsius underwater volcanoes would heat water far beyond boiling. On a percentage of heat the tea would win.
Polystyrene
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
tap water
a cup of water that is boiled since it gives more heat.

Cup,teapot,kettle,pail,tub
Because there is more water in a bucket than in a cup, and more energy has to be put into the bucket of water than the little cup of water to bring them to the same temperature.

If the water in the cup came from the kettle, it will be cooler than the water that remains in the kettle. Since the water in the cup is more exposed to the air than the kettle it will lose heat to evaporation more quickly than the water in the kettle will. The cup will also conduct heat way from the water until the water and the cup are the same temperature, whereas the kettle is already as hot as the water it contains.
