I'm certain your Lando cape is repro. Material looks too stiff and pattern looks off.
Hard to say with Leia. Doesn't scream out repro just from those pics.
The Vader ridge patterns seem very pronounced and the cape looks stiff/thick from the pics.
What are the arm holes like in the the vinyl capes? Are they evenly cut and round? Is there any wear on the capes to suggest age? Are the capes flexible/soft? Are the cut lines around the edges of the capes even?
