Please Help! 9-week old barred rocks and others

[BarredRock8]

Hey so this is my first post on here!
My family and I are raising our first batch of chickens for eggs and we need to know the gender. Our neighborhood is letting us have chickens, just not roosters, so I want to know ahead of time who are the roosters and if we need to get more. We have eight 9-week old chickens, 6 barred rocks, 1 Americana and 1 Silkie. We have no idea on their genders. We think that about 3 of the barred rocks and the 1 Americana are all males. We really hope to have at least 4 hens. Please let me if you can help us gender them! I’ll put down their name, personality, and a picture below.

Rodriguez- Confident and Bitty

Gemini- reserved and cautious

Merlin- confident and independent

Suka- Aloof and independent

Calypso- confident and friendly

Hazel- very friendly but cautious

Bongo- very friendly and confident

Mars- friendly but cautious

I say hens on all the barred rocks. Combs are too small for a 9wk barred rock cockerel.
Here is a pic of what a barred rock cockerel should look like: https://www.backyardchickens.com/th...er-needs-a-new-home-orange-county-ca.1138728/
I also think hens on the easter egger and silkie... but I am less experienced with silkie gendering, so I cannot place all my chips on that one.
