These are juvenile birds and are too young to tell. When they have their first molt around 4 months of age they will change to either browns or blue, and the blue will be truly, truly blue, not pink to purple at all. I am a budgie breeder, in case you wonder if I am a credible source.
shadow looks like a young female. purple or pink ceres as babies are usually males, any with white rings around the nostrils are female. but certain mutations can make this harder.
this site has an excellent photo guide for sexing young budgies

It is true that they can be sexed younger, but due to the color changes in photos I would not be confident doing so by picture. Sex related fights should not start before they we four months old, however.
Also bear in mind that with some color mutations, the cere is not the typical blue or brown. Twigs for example is a recessive pied, and he is at least 2 yrs. old (?), DNA'd male, and kept the same pink/purple cere and dark eyes of the juvenile.
I've never had a female Budgie, but I've heard that they don't sing (go on and on twittering) as much as the males do. Males are typically very noisy.
