What does
2 * * * *
means in crontab context?
I want to run my program every 2 minutes; is that what 2 * * * * means?

Not quite; that means every 2nd minute of the hour (i.e., 6:02, 7:02, 8:02, etc.). To make it every 2 minutes, use */2 in the first entry:
*/2 * * * * my-script.sh
You can read more about the crontab syntax and available options here at Wikipedia. Ubuntu's got a good overview too.
