These aren't typical users, but rather a processes that the system uses internally, for example, to shutdown the system - it will simply invoke the process of shutting down.
Also, generally users usually takes numbers above 500 in this file, and numbers below 100 are reserved for system use, as in this case. As you can see, they have no shell assigned.
There's also a legacy reason - on some older Linux distros you could use SU to these users and shutdown the system.

consolehelper
CONSOLEHELPER(8) System Manager's Manual CONSOLEHELPER(8)
NAME
consolehelper - A wrapper that helps console users run system programs
SYNOPSIS
progname [ options ]
DESCRIPTION
consolehelper is a tool that makes it easy for console users to run system programs, doing authentication via PAM (which can be set up to
trust all console users or to ask for a password at the system administrator's discretion). When possible, the authentication is done
graphically; otherwise, it is done within the text console from which consolehelper was started.
It is intended to be completely transparent. This means that the user will never run the consolehelper program directly. Instead, pro-
grams like /sbin/shutdown are paired with a link from /usr/bin/shutdown to /usr/bin/consolehelper. Then when non-root users (specifically,
users without /sbin in their path, or /sbin after /usr/bin) call the "shutdown" program, consolehelper will be invoked to authenticate the
action and then invoke /sbin/shutdown. (consolehelper itself has no priviledges; it calls the userhelper(8) program do the real work.)
consolehelper requires that a PAM configuration for every managed program exist. So to make /sbin/foo or /usr/sbin/foo managed, you need
to create a link from /usr/bin/foo to /usr/bin/consolehelper and create the file /etc/pam.d/foo, normally using the pam_console(8) PAM mod-
ule.
OPTIONS
This program has no command line options of its own; it passes all command line options on to the program it is calling.
