Hi, the holder can hold 2 square filters + 1 Circular polarizer filter 

Could you please update us your full Minolta lens model ?as Minolta has MD MC and AF mount, K&F Concept MD-M4/3 is suitable for: Lens: Minolta MD MC Mount lens(not for Minolta AF mount: KF06.157) Camera: Micro 4/3 (MFT) mount mirrorless camera like Olympus PEN, OM-D series, Panasonic Lumix DMC-G1, G2, G3, G10, GX1, GH1, GH2, GF1, GF2, GF3, GF5, GH4, Panasonic AG-AF100 Mirrorless Digital Cameras, Black Magic Pocket Cinema Camera (BMPCC) 

Yes, the Nikkor 50mm 1.4d is an f mount lens so it should adapt just fine. 

I don't have that lens with me. On the inside of its lenscap and on the ID on the lens, there should be the size of filter needed. If it requires a 58 then you are fine. There are also adapters to go up or down. 

A polarizer is actually two pieces of glass set in a filter ring that screws onto your lens. The outer piece rotates, and as you look through the viewfinder you'll see the effect of the rotation. so when attach it to lens please make sure you rotate with the inner gear-shaped ring instead of outer piece, or it will rotate for 360
