I agree with this.
The first male would be the best bet with the first female. They would have a better "steady" color and the fins wouldn't be as crazy and bad as the rest of the males. It's had to get red wash out of bettas so again I'd just stick with the two I, MrVampire, and Kfryman has suggested.
That steel blue HM male doesnt look very nice mostly because of his dorsal, but the first male you posted has nice color and finnage with the dragon scaling and the caudal being a nice full 180 spread.
