Could anyone help with breeds of these baby chicks and pullets?

Hello to everyone, they are the new members to my family. They were brought from a country market. The seller of baby chicks (1-4) said they are good layer but didn't tell us their breeds. Also the seller of 5-7 didn't tell their breeds either..Would anyone help me to identify their breeds? Thank you very much!
