Switching from Bridge to Lightroom Classic (Mac)/Lightroom on iPad

Hi,

For the last few years I used Bridge & Photoshop (which are up to date) to arrange, labeling & edit my photos. All of the photos (around 1.5 TB) are backed up on an external hard drive.

Recently I bought an iPad Pro and want to arrange & edit everything on the iPad, using lightroom and photoshop on my iPad.

As I plugged in my hard drive to the iPad and opened lightroom, I saw none of my photos had any labels or ratings in lightroom (for example, if I had a photo labeled in bridge as "Approved" (a green label) - in lightroom the photo doesn't seem have a label). Also seems like the camera raw settings of my photos (which I set in bridge) does not exist in lightroom.

So my questions are:

1) How can I see the photos' labeles, ratings & camera raw settings (which I defined in bridge) in lightroom?
2) Can I edit photos in lightroom on my iPad straight from my hard drive, without importing them to lightroom cloud? ofcource I have too much photos to import them all.

*If that helps, I just downloaded a lightroom to my computer. Still, can't see any labels, ratings or camera raw settings in lightroom.

Thanks!
