It is not a good idea to mix lamps and ballasts. Ballasts are designed to output a specific voltage for the lamp that it is designed to be used on. By suppressing a wrong voltage on a lamp can shorten its life expectancy by a good deal.
No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.
It will power two 400 watt lamps.
The amount of light produced and the amount of power consumed. A watt is a unit of power and electrical power is determined using the formula: P = I2*R , Where P is power, I is amps and R is resistance. But using Ohm's law ( V = I * R) the following can be obtained: P = V2/R , Where V is voltage. In US house holds the standard voltage is ~120V, changing the resistance of the filament of the light bulb will change the amount of power consumed and therefore the amount of light produced. The higher the wattage the lower the resistance of the filament. Filaments are used in standard incandescent light bulbs and not in fluorescent tubes or LED fixtures.
Remember that dimmers are for incandescent lights only unless you invest BIG BUCKS on dimmable fluorescent lights and fluorescent dimmers. Make sure that the switch that you replace with the dimmer does not control a plug-in outlet unless it is a lamp. You could do harm to an appliance not designed for such use. Otherwise,just add up the wattage of all the bulbs on the dimmer and buy one of the next size rating. So if you have two 60 watt bulbs, two 75 watt bulbs-- that's 270 watts total.Find a dimmer rated for 300 watts or more.
The bulb will have an efficacy of 17-20Lm per watt, so in total 500W = 8,500-10000 lumens. However, the bulbs light output is non directional, so a lot of the spilled light is in directions that you don't want it to go, so 50-70% of the figure can be used when specing up an LED variant.
I would wire them together in a parellel circut. all the lights together, white to white black to black then put your ballast to em. it works like that with my 400 watt mh/hps ballast and 2 250 watt hps bulbs. run 2 hps bulbs with 2 mh bulbs if you can, you get better results.

No, you can not use a 150 watt high pressure sodium bulb with a 70 watt ballast.
no you cant if the ballast is for a 150w bulb you have to retro fit the ballast then u can
430 watt bulbs are made to juice a little more light from a standard 400 watt ballast. you get about 3-5000 more lumens. A typical 400 watt HPS produces about 50-55,000 lumens. The 430 will put out about 58,000. Not a lot, but a little extra without any increase in power usage.
Yes assuming the ballast is also for a metal halide lamp.
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all
Yes.
If both bulbs fit into the same socket I would presume this to be fine.
yes The higher the wattage the greater the heat. the filaments in each wattage must be of a greater diameter to handle the current. if the filaments are of a greater diameter ergo they draw a greater current from the voltage supplied.
the 35 watt lamp will work in a 40 watt ballast.
Not recommended. It would work but shorten lamp life and may cause risk of fire. However, if you just wanted to check a lamp was capable of striking it would be ok for a few minutes. I've done the opposite in the past and used a 150w lamp with a 100w ballast. Works, but not good for any of the components, including lamp.
