    root:x:0:0:root:/root:/bin/bash
    web1:x:5004:5005::/home/web1:/bin/bash
    
    I don't create user for Jailkit and is normal root access?
    How-to remove this users from Jailkit and remove folder lib home .ssh etc..
    Thanks.

    Jailkit is not only used for jailed shell users, but it is also used for cronjobs as well. Don't remove these folders and the local jail passwd file is fine, it odes not grant root access.

    Yes, that looks like a normal jail as it's used for shell users and for cronjobs.
