Can't identify these hardlines

As the title states I have some hard lines that have been blocked off since I got the car which is a JDM 90 s5 turbo. Well I'm pretty sure one of the caps blew and sprayed oil everywhere. Just need help with what lines they are so I can go from there. Thanks!

from there. Thanks!

Top one with the threaded hex fittings is the turbo oil feed. Should run to the top of the turbo. Bottom two are vacuum (although they don't actually see vacuum, just boost) are the lines for the factory boost control solenoid. One line runs from the turbo compressor housing to the solenoid. The other runs from the solenoid to a check valve at the back of the intake elbow behind the MAF sensor.

Alright so I should be good just capping those back off. Is it normal to have that much oil in them?
