Hi Heena, New Buttion: Yes you can override the default new button with your custom VF page. Save Button: If your save button is on the standard layout page then you cannot override the functionality of the save button. But if your save button is on a custom VF page then in that case you can definitely override the standard functionality.
Please mark it as the best answer if it helps you so that others will similar query can benefit from this post. Regards, Naender.
