Custom loop for plugin

Hello guys, I’m developing a plugin and now I came across the following situation. The plugin has a custom post type, which is stored one custom taxonomy.

Each post contains a repeater group metabox, which allows the user to enter 3 images and 3 titles, these images and titles are displayed as a grid on the frontend.

So far everything works fine, I have loop that takes the custom posts types that are stored in a specific custom taxonomy and can display a slide in which each custom post is equivalent to a slide grid.

My difficulty is the following, if at a given time the user needs to insert dynamic information inside this loop, how do I stop the loop, make a new loop and then return to the initial loop?

I put down the link of an image that might help.
