Does anyone know how many breather lines the first gen liberty's have and where they are located(differentials, transmission, etc.) I want to raise them higher when I do my lift kit just so I don't have to worry about it later.
Also what would the process be to extend them?

I believe both diffs and transmission have breathers. My rear diff's was dry rotted so just replaced it with some hose from Autozone. I think rather than extend that one you should just replace it - it's pretty short anyway. I don't recall exactly where the front diff and transmission breathers vent but just look for a couple of open ended hoses in the engine bay, or trace them up from the diff / trans. Again, it may just be easier to replace them than extend them. Are you planning on fording deep water? I never worried about it when I did my lift. Assuming you know that you'll need to modify the hydraulic brake hose mount at the rear axle or else you risk ripping it off at full flex. Not sure if there is a height of lift beyond which you risk the front brake lines? Mine seem OK with a 3ish inch lift.

I'm planning on 3 inch lift and don't plan on deep water, but better safe than sorry

The landrover enthusiasts round here extend all the breathers to the airbox for deep water fun.

I think the front diff breather terminates on top of the left side wheel well near the battery tray. Should be some weird looking plastic vent cap stuck on a stud under there.

My KJ's front differential breather was cracked under the battery.
I cut it about 20mm and reconnected it.
I did that as a stopgap, but I just remembered it.
Since it seems unlikely that the differential oil will exceed 200℃, I will replace the hose with a heat-resistant silicone hose.
The parts list says that both the front and rear hoses are 5/16 hoses.
It would be a big problem if the differential side was cracked.
