Please Help Identify Platy and Molly Genders. Pictures

I would be very thankfull if someone could give me a second opinion, I am not the greatest yet at picking out which are which. I have labeled them all. If you could give a reasoning for what tells you the gender, it would be great.
Thank you so much.

Most livebearers are fairly easy to sex. At sexual maturity, in platys this occurs at around nine weeks, male and female anal fins start do differ. Females will have a fan( triangle) shaped anal fin. Males will have a modified annal fin known as the gonopodium. This modified fin is penile in shape. I cant see your pics but hope this helps

Look for a triangular anal fin for a girl, and a pointy anal fin for a boy. From your pictures, Golf is a girl and Kilo looks like a boy (but sometimes the girls can swim around with their anal fin tucked up so you need to watch them swimming around to see if the fin stays pointy.)

Possible #1 is but can tell with clarity.

The others you will have to watch. Females also clamp the fin tight. But males will flick it down or to the side occasionally (especially if watching female).

But it all depends on the age. If these are very young fry....those appearing to be females may just not have developed the length of the pendulum. Watch for tip to elongate if such is the case. Or for them to flash it to right or left.

Good luck. They look good and healthy. When you do more pictures try and clean the tank glass so water stains and dust don't obscure the pictures.
