Can I display multiple size charts for each product?

yes! 

There are 2 ways to go about it.

One way is to create multiple sizing tables for the same sizing chart. On the page layout section, you can add multiple tables.

Another approach is to create multiple sizing charts for the same product. When visiting a product page, all the sizing charts matching that product will show up, and they are ordered by the creation time of the sizing charts, with the newest size chart appearing first followed by older size charts.

So let's say you have a product which is a bundle of t-shirt and jacket. Create 2 Kiwi sizing charts, one for the t-shirt and the other for the jacket. Now the way you would set up the product matching conditions can depend on the use-case. You could specifically set both sizing chart to match the product bundle or if the product bundle has "tshirt" and "jacket" tag, use those as matching conditions.
