Is this homework? If not, what have you tried so far?

No, it is not a homework.

I tried list the file then send to tmp file, then using diff to compare. but it doesn't work
ls > tmp
diff tmp filelist

You could use a while loop to read the file names from the file: filelist and check each one in the dir: /home/abc
Code:
while read file
do
        [ -e "/home/abc/${file}" ] && echo "File: $file does exists" || echo "File: $file does not exists"
done < filelist

Code:
#!/bin/ksh
d='/home/abc'
fileList='./filelist'
while read file
do
if [ -f "${d}/${file}" ]; then
   echo "${file} exists"
else
   echo "${file} does not exist"
fi
done < "${fileList}"

Those grep options cannot cope with whitespace nor characters that are special in BRE grammar (most notably, the dot). Instead of -w, I would suggest -xF.

Minor nit: -1 is redundant.
