the 2 lines on the left I believe are hydraulic lines for the brakes/leveling. The 3 to the right are fuel and vent, not sure which is which tho so I guess I am of no help. one pressure, one return and one for the charcoal canister ventilation. You may be able to back track them from the hood area as they will be in the same position to the rear.
you could soak the center one with a rust treatment to stop the continuing rust while you figure if it's a high pressure line or the vent.
