It does have the coloring of a silkie but I don't see any sign of a crest, it should have a little poof on its head, does it have feathered legs? It might be a silkie with a smaller crest.
First ones not a silky, second is white crested black polish, next two not sure, fifth one is either an Ancona or exchequered leghorn, last is possibly a Millie Fleur d'uccle. It would help to see their legs to know if they are feathered and what color.
