Your error message comes from a single quote. The colon is part of the error message.
For example in my version of shell if I issue "unset $num" when I should have issued "unset num" and $num contains a single quote character.
num="'"
unset $num
sh: ': This is not an identifier.

You cannot get your error message from the code you posted unless a student number contains punctuation. Are you showing us the whole script? What do you type?

Maybe try the script with quotes.

echo "enter student number"
read num
echo "${num}" > ./st/file1
