Gender of these 5-7 week old Chicks?

[ChickenJames]

I am sure these are ayam cemani chicks that shouldn't have a mix seeing as how the breeder I bought these from had a few males and females that looked like they were pure. What I'm looking for isn't the gender of these. I also want to know the gender of these Hmong chickens. Both are fibromelanistic breeds. They will be labeled by alphabet abcdef... I look forward to your guys' feedback.
A.)

Head and body pictures of this one.
B.)

Didn't take a head picture. Hard for me to tell these ones apart.
C.)

This is a Hmong chicken.
D.)

This one to me looks like a female.
E.)

The largest of the Hmong chicks. I am 99% sure this is a male as he is a head taller than the others.
F.)

Also am 99% sure this is a male too. This "guy" is taller and has longer tail feathers than the other gray chick.
G.)

Am not sure about the gender on this one.
H.)

Ayam Cemani. Smallest of the ayam cemanis and also youngest probably. I don't know gender
I.)

Oldest of the hmong chicken I believe. Looks like female to me.

That is all of my hmong and ayam chick s I believe. Looking forward to the feedback on their genders.

Oh whoops, read it wrong. I’ve never heard of Hmongs until now.

Yeah pretty ugly looking chicks but they look good when fully grown.
