Wow, they are all great, so keep all of them! You can wear them with anything. My favourite is #1 and #2 - such a sophisticated colour and design. Would be fun to wear with a skirt/dress in soft green. Or with charcoal pants and a light grey shirt/blouse.
I have a black coat in the same style as yours, bought in 1993, still looking great and winning me compliments. Always nice to wear over dressy outfits. But I like juxtapositions, so I occasionally wear it with items like these: blue/black straight jeans, silver fashion flatform sneakers, turtleneck pullover and a beret.
The black leather jacket could be fun to wear with checked black&white pants/skirt and red boots. Or you could style it with a silver grey or purple elegant skirt/dress and dressy shoes.
