The service panel itself is probably less than $200.

No, you can use the six main rule. This means you would have a 400 amp main lug panel, with six breakers or less, but no more than six. You can also use six individual disconnects.
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.
Water is a liquid at this pressure and temperature.
400 Kelvin is equal to 126.85 degrees Celsius, or 260.33 degrees Fahrenheit. At this temperature, water has boiled, and is a gas (steam).
The type would be a three phase panelboard. If you are carrying the wye neutral into the service, then it would be a three phase four wire distribution panelboard. Regardless of the style used, it would have to have a minimum 400 amp bus.

Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.

500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.

noAnswerWhereas most countries have single-phase residential supplies, some countries, such as Cyprus, often have three-phase supplies. The main distribution panel ('consumer unit') must be designed and assembled to accommodate either a single-phase supply or a three-phase supply; you cannot use a single-phase distribution panel with a three-phase supply.

If the phase voltage is 230 V, then (providing you are describing a three-phase, four-wire, system), then the line voltage will be 1.732 larger -i.e. 400 V.
