I absolutely love this, keep it up!

great!
Is this link from Four Swords Adventures?

So if I understand this right, we could say this was Linked Universe before Linked Universe was a thing, isn't that so?
I hope in revising your story you will keep it distinct from that A.U. so as to keep things fresh and interesting. For one, am I correct in assuming that Minish Cap Link isn't also the one from Four Swords and Four Swords Adventures? And that TP Link won't be able to turn into a wolf since Midna normally carries the crystal that changes him while he's in hylian form?

A funny thought: I never considered what it'd be like if OoT Link met some of the others while in Termina. Imagine if he were to assume he's found his counterparts (I mean, he did find two Malons of different ages). That would get confusing quickly!

Hecking Majora, trying to destroy everything. I guess that's what it does and all, but Link deserves a vacation, completely free from all demon-possessed masks.

Huh, apparently I'm first. Not bad, mate, not bad at all. So the discomfort they are getting is the universe imploding? Interesting. Suprisingly few authors of these kinds of stories have the characters physically impacted by the world ceasing to work correctly. Occasional punctuation errors, but hey, I won't judge. My typing is generally a mistake-filled trainwreck that takes a long time to proofread, and I inevitably miss most of the typos. Overall, definitely not a bad start at all. Keep up the good work, mate!
