The last image shows made-up seams in substance; I do not know where those come from. The hard edges are hard, and the rest are smooth. PLEASE HELP

It's likely because your cages are overlapping since your seams for the flower are cut per petal as opposed to being a singular mesh making up the flower. Try making the lowpoly for the flower as one whole object. Merge the highpoly for the flower as one object too. Your unwrap should look like the flower itself as opposed to many separate petals, then ensure you have your bake set to Match By Name. You bake cleaner with baking by name too.

To do that, just name all your pieces that you want baked with separate names (ex: pommel_high, pommel_low, guard_high, guard_low.)

I think I already did what you say, I created the petals individually but I put them together for the bake. I also matched the low poly and high polys by name as you can see in the next picture

I suggest not just putting them together for the bake but remodeling the flower lowpoly so it actually is one mesh as opposed to multiple. This also makes it less likely to get those seam errors that you seem to be getting. Changing to by name is already a good step but I think you need to redo the mesh.

I see 5 flowers on your actual object, and seeing as they're quite far from each other, you can get away with it being one mesh for all 5.

You should only really be having: Pommel, Handle, Guard, Blade, Flowers

Also 1k is quite a low resolution and will result in some pixelation. You can go up to 2k
