I hope you don't plan to use all of them🙊😜 As many of these are acids. I would recommend exfoliation acid use max 2-3 times a week, especially with sensitive skin. I personally find it best to not use too many active ingredients on my skin in a week. So I would chose only a select few of these.
You could do a schedual like
Day 1: Acid/exfoliation day (choose 1 of the following: BHA Peeling, AHA/BHA Toner, Mandelic Acid Skin Prep Water, Aloe BHA Toner, Tranexamic Acid Serum OR Tone bright Ampoule)
Day 2: rest day
Day 3: rest day
Day 4: Acid/exfoliation Day (Choose the same as day one's choice)
Day 5: rest day
Day 6: rest day
Day 7: rest day
Start with only using acids 2x a week once well tollerated you can increase it to 3x a week. Pay attention to your skin barrier. Using exfoliation acids too often can damage your skinbarrier. When choosing your acid to use note that Mandelic Acid is known to be one of the more gentle exfoliating acids for sensitive skin. This could be a great product to start with on the acid/exfoliation day.
Use the efoliating acid product at night. Always make sure to use SPF during the day. If you do not use SPF then please never use acids/exfoliation cause it makes the skin more prone to burning, aging and skincancer as you exfoliate the top layer of the skin. SPF use is super important when doing this❗️
In your morning routine you can choose to use Niacinamide and/or Azelaic Acid depending on how your skin react to it.(Azelaic Acid unlike the other Acids can be used daily and is pretty gentle and great for Rosacea redness). Not everyonce skin is a fan of Niacinamide so try out and see how your skin responds. You could alternate, one morning Niacinamide and the other morning Azelaic Acid. You can use them both every day in the morning routine as well if your skin tollerates it, but as you have sensitive skin I would recomend staring with alternate days and see how that goes😊
Last not. I would recommend not beginning all these at the same time. If your skin get's irritated it is difficult to know what product causes is. So you could start with incorporating the exfoliation nights first, few weeks later add Niacinamide in mornings, and a few weeks after that start using Azelaic Acid. This way it will be easier for you to see how your skin responds to each product😊
