Pathfinder Bestiary Pawn Box (P2) Game

are these printed with front and back? i.e. front of pawn is front of monster and back of pawn shows back of monster?

What size are the medium bases? I use a map grid of 1" pers square. Will these fit? Are the other bases appropriately sized as well?

Are these the same monsters but different artwork that are in first edition beastiary pawns box?

will the box fit the other pawn sets from bestiary 2/3? and has anyone used an insert for sorting?
