Definitely cardinals

Females are likely to be fuller bellied but it's not always easy to tell male from female. You can be sure you'll have a mixture in a group that size.

I can see the odd white spot on the fins of your cardinals. This could be debris in the water or a disease called ich. Can you tell us if the spots are on the fish??
BTW cardinals need a bit warmer water than neons so it’s good that you asked.

I see them too; I see in one of the images that the spots are blurred with fish movement.
