Can I create templates for Paragraphs created using the Paragraphs module?
Yes. You can create templates for Paragraphs but you'll need to implement some hooks to make it work.
If you want to use Paragraphs for content layout rather than DX8 components or your existing website uses Paragraphs and you want to use the power of DX8 to create templates for them you can implement some hooks to make DX8 work with Paragraphs. Here's a developer guide Implementing hooks for custom content entities.
