Various trance/acid trance from 90's

Hi!

Please help to identify the following trance tracks by attached excerpts.
I'm assuming that most (if not all) of them are from 90's.
Most of tracks are acid trance, the only non-acid are: 1, 2 & 5.

Any hint is appreciated ;) Thanks in advance!

Identified tracks:
2 = Cee-Jay Bolland - Planet Zorgon [R&S Records]
3 = Space Dimension - Sumerian Dawn [Alien Reign]
4 = Space Dimension - Sectors : Five, Six And Seven [Alien Reign]
5 = MicroWorld - X-Pression [Waf Waf]
6 = Zen Paradox - Mescalito [Nova Zembla]
7 = Lost Sector - Red Shift (Sonar Mix) [Fishtank]
8 = Felix Da Housecat - Footsteps Of Rage (M Plant Mix) [Radikal Fear]

Any ideas?

What do you think?

Anybody? 3 tracks left (1, 3 & 9).
