In that case, there are a few options:
--If all the labels are right, you probably have just pullets of the breeds they said. There is a chance of one or two being sexing-error males, but probably not many, and they are not particularly obvious right now. So you will have to wait and see.
--If some or all of the labels are wrong, then you may have wrong genders and/or wrong breeds. Trying to check the sexlinks by color is hopeless if the labels might be wrong, because they could easily be other breeds where color does not tell you anything.
Either way, I do not see any really obvious males, so I think you will just have to wait and see as they get older. Some pullets do grow their combs faster than others, and all of yours are within the range that COULD be either a female or a male at this age.
