1). 1st one is Air Liquide - Robot Wars: Combat Zone Part I.
Air Liquide - Robot Wars: Combat Zone Part I - YouTube Air Liquide - Robot Wars (Vinyl) at Discogs
The funky beats part is just a sample the dj is mixing in.
5). Why such a small sample for "Unknown 5?" At any rate, it's from Simply Jeff:
X-Calibur - Someday / Got It (Vinyl) at Discogs
If you want to know specifically what that 4 sec. sample came from, who knows? Maybe they just got tribal on some Kava Kava, and chanted it themselves. There's only 1 mix of that "Got It" track that made it to yt:
X-Calibur - Got It (Bonus Beats) - YouTube
6). The #6 unknown is just a longer piece of the above "Got It" track.
2). Why don't you listen to the other guy about the Mantronix, because the sample you are giving us could very well be from that record. From the sample you have given us, the subtlety of a "house beat" cannot be determined. Definitely, it is faster; that's what a pitch knob is for (speed up, slow down). Sure, the guy cuts out the channel a bunch of times - an old dj mixer trick. He may even be using 2 copies of the same record. It does not sound that different (or maybe you'd like to give us a longer sample) from what we can discern from your short, low quality, & low volume (I opened it up in a waveform editing program and it's like barely -15 dB) sample.
