What would you do if you had four projects, one due today, one due in a week, one due in a month and one due in a year?

I assume I have all these projects now because they all require work throughout the period to deliver on their respective timings so I would lay out all the tasks and sub tasks necessary to deliver the projects on time and ensure nothing falls through the cracks. This will also help me identify any conflicts or barriers so they can be addressed in advanced.

prioritize it according to hand over schedules

I'll handle the projects in order of timelines
