so I have a gas leak under my car. I checked it out and I found 5 lines running parallel to each other under the driver's side. I'm not certain which one is leaking as the leak is coming out from where the lines are secured to the car.

Can someone tell me what each of these lines are for? ....and the ease/complexity of replacing the line? Can i cut the line and attach a rubber hose with some hose clamps?

Cheers.

yes, you can patch the leak with rubber hose...but i dont think that you'd want a soft line under the car!

2 lines are brake lines
1 is fuel feed
1 is fuel return
1 is evap from the tank to the charcoal canister.

it'd be best to patch it with hard steel line which requires a line flaring kit and the know-how to use one. if you dont know what im talking about then i'd suggest letting a shop do it.
