Most of them have been answered in the beginning. Here they are again.

1) Aolian, Dorian, Phrygian etc... as seperate entities, what are they called? (modes? scales?)

Modes. Everytime you see a name with "-ian" on the end, you can safely assume it's a mode.

2) When you get a whole 'group' of them together, what are they called? (a scale? a mode?)

Don't have any idea what you mean. Each mode and scale is it's own identity.

3) Are there always seven of those aolian type things in a full group of them?

There are as many modes as they're are notes in a scale. Like the major scale has 7 notes so there are 7 modes.

Hope that helps man. Sorry bout getting off track, thought we answered those.
