That 2nd cockerel looks like a grey; I'd need to see better photos to be sure. However, if she is showing a trio, they all need to be the same variety, and the two girls need to look as close to identical twins as possible.
Greys have patterns on the individual feathers; blues have solid coloured feathers. (Techncally blues should be laced, but you cannot see it on silkie feathering, whereas you can see the penciling of grey and partridge. IMO, I think that lacing is not very prevalent on lighter blue to medium blue silkies)
