Hello and Welcome To BYC! You might want to post pictures of your chicks in the What Breed/Gender forum, if you can get good individual pictures of them it would help https://www.backyardchickens.com/f/15/what-breed-or-gender-is-this from that picture at least three look to be males from the size of the comb. the one in front, the one farthest left and the kinda in the middle back.
Glad you could join the flock! Individual pics would be great but I too have to agree that the combs would indicate males.
Wishing you the very best of luck and hope you enjoy BYC, I am sure you will everyone here to help and very friendly
