Question 1: If you have 125 cubic magnets ( 1" x 1" x 1" ) arranged in a large cube (5" x 5" x 5") will the assembled large cube behave magnetically as a solid magnet of the same dimensions?
Question 2: In the pyrolytic graphite levitation, is there any way to increase the height of the levitation by placing another layer of magnets (4 or 9 depending on which configuration) below the first layer of magnets. If so, would successive layers increase the magnetic field strength above the magnets and subsequently the height of the pyrolytic graphite? Would this increase also effect the holding capacity (weight) of what can be lifted?

Asuming that the small magnets are made of the same materials as a large magnet, Yes the big clump of magnets should behave the same way.
Since diamagnetism is such a small effect you won't get much more levitation once PG floats past 1mm. Since you are saying to put more magnets underneath 4 other magnets then it won't float higher because the PG is too far away from the magnets. Not to mention it would be a pain to get the magnets separated. The only way you could achive higher levitation with PG is to have stronger magnets or a stronger magnetic field and magnets like the ones on this site are some of the strongest permanent you can get. If you wanted to levitate magnets you could always try superconductors.

The levitating PG project currently is done in air.
Doing it in water gets you a little higher levitation.
Doing it in a liquid with an even higher specific gravity (up to 2.09)
will get even higher.
Changing the gravitation is also an option. It will levitate higher
on the moon, or on the ISS, or in a descending elevator.
