Yup.

Yes there is variation in technology between Spheres. "Technology" is pretty much the same as it is today, save for the lack of computers and space flight. All energy is supplied in some way by mana, however, not by fossil fuels, sunlight, or wind and such. Projectile weaponry -besides bows and crossbows- are absent as well.

Hovercraft technologies have been achieved, as well as flight in airships running on gaseous mana.
