Sorry need help again. Are my seed roots done?

Heyo,
It's me again.

Ok last time you all provided great suggestions to manage my current pepper situation in which they were shrimpy looking and then later the leaves were showing possible nitrogen deficiency.

I was told it's better to keep them in a smaller seedling starter cell but right now it's too risky to move them around. So I need to manage their water and nutrition better.

Ok fine.

Now. I got some Witch stick, arapaho and jalapeno going in a bigger cell (before I got into all this mess). I started them in peat pucks as I saw root, I moved them.

Most of my jalapeno, a couple witch stick and 1 or 2 aparaho had germinated and taking root.

However, I noticed a few of my germinated ones went somewhat limp. The cotyledons leaves didn't perk up or the helmet is still stuck.

I fished around and saw that the root may either rotted off or not really developed. I'm not sure if it's because it's dampened off or something else happened.

Are these guys done for? Or should I just give them a chance and see what happens?

Since these seedlings are still very young, I think I have time to plant them into smaller starter cells.

Whaddya think?

Sorry for all these questions but I'm really struggling here.
