You can use growfs to increase the size of a filesystem (I suppose this is
what you mean), but only if you have free disk space available adjacent to
the cylinders allocated for the filesystem in question.

You cannot decrease the size of filesystem without recreating it.

Thus you have the following possibilites to choose from:

1) Reinstall FreeBSD and use more suitable filesystem sizes.

2) Backup the data of the filesystem which is too large and adjacent to
   the filesystem which is too small, enlarge that with growfs, recreate
   other filesystem with smaller size and restore the data.

3) Try to identify subdirectories containing a lot of data within the
   filesystem which is too small, move them by mv to a filesystem with
   enough free space and symlink them back (ln -s) to the old location.
   But do not move the whole /etc directory from the root to another
