Question about the Spheres in CH 1

Hi everyone, I am currently enrolled in the course and have a few questions about the spheres.

1. Is the sphere of Air, the sphere of prana or qi? Is this also the "pneuma"?
2. What is within the sphere of Souls? Is it the planetary spirits and zodiacal daimones? Is this the sphere of the Demiorgos?

3. Is the sphere of Matter made out of the elements of Earth and Water only? According to the Salaman et al., translation it appears that the negative elements of Earth and Water were below and the positive elements of Fire and Air were above.

   Thanks in advance for your input. I am enjoying the course so far!
