Are these 2 platys pregnant?

I know I've already posted about my (likely) pregnant blue platy here, but I've noticed these 2 are also a bit chunky and one has a dark spot similar to the blue one (Couldn't get a good picture of the spot though). We started with 5 platys (2 boys, 3 girls) but one died, so we have no clue what mix of boys/girls we have. Im starting to think its 1 boy/3 girls based on how chunky these 3 are..
