SQL is a descriptive language, not a procedural and it does not support constructs like loops. You'll have to construct the loop in the shell script and call the sql-client within this loop.
Does the sql-commandfile cancel.sql already accept the parameters? The first paramerer (in cancel.sql) is referenced as &1 (unless you changed the default via set define).
I would put all SQL*Plus commands (WHENEVER, SET... and SPOOL) into cancel.sql and then write your script like this if you are sure the file Cancel_ID.txt is always in the correct format (maybe validate that as start of the script):

Code:

#!/bin/bash
# read first line holding the parameter until there is nothing more to read
while read CANCEL_ID; do   
   sqlplus -s user/password@universe @cancel.sql $CANCEL_ID
   sql_return_code=$?
   if [ $sql_return_code != 0 ]
   then
      echo "The Cancel.sql script failed. Please refer to the log results.txt for more information"
      echo "Error code $sql_return_code"
      exit 0;
   fi
   # read second line and ignore it
   read DUMMY                     
   # read 3rd line and ignore
   read DUMMY
   # read empty line between the paragraphs and ignore
   read DUMMY                  
# feed the file to the loop
done <Cancel_ID.txt

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
