I've heard all of them before back in 2001.
However I can only remember then name of the first track. It's Nexus - Return From Flatliner
I recommend you to go through Gary D's D-Trance CDs and Tunnel Trance Force CDs from 2001. I'm 99% sure that you can find the other tracks there.

Any other info, like where you heard them?
Simcut
01: Nexus - Flatliner
02: Sounds like a Hennes & Cold Remix of a track....dunno what one
03: Flat 6 - It's Too Late
04: Sounds like Freejack / Alpha Breed or Vincent De Moor, I have it, let me find my vinyl.....

I was going to say #2 sounds like a DJ Scot Project remix of some track.
