What is the ruling on the Ramadans that I did not fast, do I have to make them up, and what should I do as I intend to perform Hajj this year?

You have committed a grave error by intentionally breaking your fast in Ramadan. You must repent sincerely and make up for the days you missed. If you broke your fast by intercourse, you must offer expiation (kaffarah) in addition to making up the days. Furthermore, according to the majority of scholars, you must pay a fidyah (ransom) by feeding a poor person for each day you delayed making up the fast. Do not delay making up the fast unless there is a valid excuse, and strive to perform it so that your repentance may be sound.
