Can you give us some more photos and context as to where you found these seeds? They really could be any variety. The pink one in the middle, and the redish-brown in the bottom left are not that common for pea seed coat colors. But even then it would be hard to identify based on seed.
p.s., what part of the world are you hailing from?
The red brown pea on the bottom left appears to have the marmorated seed coat trait (as well as the black hilum one) This is usually found among older types of soup peas (Carlin, Maple and Latvian come to mind) but is largely excluded from modern ones both because the seed coats are thicker and tougher and because colored seed coats like that are often associated with higher amounts of various substances that can make the peas taste bad.
The pea in the center looks like it has the orc (orange cotelyedon) gene (the pink is actually orange filtered through the white of the seed coat) If you are interested in growing soup peas (which all except the top right probably are) this can actually be a good gene to propagate, as the orange peas are high in beta carotene (much the same as red lentils).
