Yes, you can display the elements in a for loop. It's a little hairy. I added to end of script. There is also ${#file[*]} (even more hairy), which is the number of elements in the array, and could be used for same purpose.
Code:
$ cat test.sh
FNAME="abc.txt,def.txt,ghi.txt"

awk_ndx=1
sh_ndx=0
while [ 1 -eq 1 ]; do
  filename=`echo $FNAME | awk '{ print $n }' n=$awk_ndx FS=","`
  [ "$filename" = "" ] && break
  file[$sh_ndx]=$filename
  awk_ndx=`expr $awk_ndx + 1`
  sh_ndx=`expr $sh_ndx + 1`
done

echo all values = ${file[@]}
for a in "${file[@]}"; do
  echo $a
done

Code:
$ ./test.sh
all values = abc.txt def.txt ghi.txt
abc.txt
def.txt
ghi.txt
