Help me Identify this part please.

Take a look at the picture and let me know what you think it is. It's pretty soft and has a nick in it. It runs from the top of the radiator all along the side passenger side of the car where it clamps on into the firewall. I don't trust it and want to fix this before I drive the car.

I think it's heater radiator hose. But not sure. Is it #1

There are two hoses it's the one closer to the fender. Which looks like a real BARE to replace. I cant even see the clamp. Let me know if you have any tips on how to remove or replace.

Yup. That's a heater hose. Goes to the heater core. Need to get the hoses off the core bibs from underneath.

I've replaced the heater core hoses. They are not easy and the lower one on the core needs to be removed from underneath. The upper hose on the core can be removed from the top once the cabin airfilter base is removed. The hose you want to replace goes to the lower bib on the heater core, so you need to get it from underneath Pull the airbox and cabin airfilter base (we all call it the cowling) and trace the hose. The hose in your picture has a different connector at radiator hose bib than the N52 does, so I can't advise how to remove it, but the new part would give you a clue.

I did a DIY for the N52 a few years back. This is what I wrote to get the lower hose off:

Lower Heater Core hose: This has female BMW plastic connector on the heater core side. It is already disconnected on from the radiator hose. To remove it from the heater core, release the BMW Clamp. The spring clip is on the bottom of the connector and pulls down. It is difficult to reach from the top, but can be reached from the underside as long as the fuel/brake hose guard is removed. Good news here is since the BMW Clamp mounts to the aluminum hose bib at the heater core, it comes off very easily. Wiggle and pull it off the heater core.

I have a lift, so the lower hose was not too difficult. If you remove the upper hose to the heater core (which has a spring hose clamp) you probably can get the lower one off from the top side.

Good luck with it.
