most likely you created and edited the groups whilst still having the
shell open, it wont pick up any new groups until you start a new
session, or run newgrp.

not quite, you can only have one 'active' group at a time, ie the group
that your files will be created as by default, in the abscence of a
group sticky bit on the directory.

as far as access permissions go, your in all of your groups all the
time.  you just wern't a member of that group when the shell was
started. the id command will have showed that group missing from the
list.
