As this is acrontabfile, are you sure you want to replace all those fields with "shivam" -- or did you want to change the command that comes after them, on the same line? What are you trying to do?

Double quotes have no special meaning in sed, they match double quotes literally. If they don't appear in the source text, remove them from the pattern.
Asterisk, on the other hand, has a special meaning in sed (it means zero or more times). To match literally, it needs to be backslashed.
sed 's/9 3 * * 3,6/shivam/'
