The average size water tank is 4500 watts. The generator's supply will be large enough to operate the water tank. Larger tanks over 5000 watts will not heat correctly.
No! It doesn't matter if you use two legs or three. The output is 5000 watts
Not if the furnace exceeds 5000 watts.
Yes, voltage effects the output of electric heaters. The wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms. Applying 220 volts on the same heater whose resistance is 15.43 ohms results in this new heater wattage rating. W = E (squared)/R = 220 x 220 (48400)/15.43 = 3137 watts. W = watts, I = amperage, R = resistance in ohms and E = voltage.

Yes, you can but the wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms.

W = watts, I = amperage, R = resistance in ohms and E = voltage.
You can find a 5000 watt generator by looking online through www.ebay.com or through www.craigslist.com. When you purchase online you can have it shipped to you and sometimes score free shipping.

yes
If it's a dc generator it would produce 2/5 of the voltage at the lower speed, and another factor of 2/5 less if the armature supplies the field winding. So the voltage output could be 16% of the rated voltage. The current limit would be the same, so the output would be 71 watts maximum.
yes
5000 Watts if it runs ideally. It really depends on the generator's efficiency. Lets say, if its working on 80% efficiency, it'll provide with 0.8 * 5000 watts of electric power.
