The field descriptions are:

the (encrypted) group password. If this field is empty, no password is needed.
GID the numerical group ID.
user_list
a list of the usernames that are members of this group, separated by commas.

As the 4.2BSD initgroups(3) man page says: No-one seems to keep /etc/group up-to-date.
