Tune ID 10 - Piano Tune - Peshay - Good Looking Records
Tune ID 12 - Hes either in the mix or its a remix of Jump - Studio Presha EP - Certificate 18 records (Photek)
Tune ID 13 - Sounds like it could be a rufige Kru on reinforced, not 100% it just sounds like them
PS Tune ID 8 - could be another track from the Studio Presha EP - Water Margin???
ID 10 is 100% ID 12 is about 90%, the tune came out on cert 18 recordings then I remember it coming out on another label so there are a few mixes of it and I don't know which one it is. The other two are just speculation on my part.
