Concerning the first photos - Left is a definite cockerel, right is a definite pullet
Chipmunk chicks have nothing to do with gender, has to do with color. The better the striping on a chipmunk the more pure duckwing it is. Now, a light yellow or white one with weak but definitely stripes, yet broken at times, is likely a male though. One with thicker stripes can often be a female, but, it really is unpredictable. Depends on parents.
As the chick ages best to sex EE's by color once they're 6 weeks old. Males will have yellow or red in the neck, back, or wings. Females will either be brown and black marked all over or black and white marked all over, but some can be mostly white or brown too. Just no serious red coloration, no serious yellow coloration.
