Are these pullets or cockerels?

[Marshaharrell]

We got 5 Super Blue chicks at one week old, hoping for a few blue egg layers. From the beginning, one was obviously a rooster, although he was the runt, and we called him Roo. We thought the rest were hens, but then a few weeks ago, another one started crowing and was christened Geronimo. Now, we have doubts about two of the others. I believe they are around 13 weeks old at this point. Pictures online are really confusing, as it looks like the sexes don’t look that different. Any ideas?
