Absolutely, by a margin. There's definitely a hint of that in the ALC obituary describing him as king of Meath, Bréifne & Airgíalla. As far as I can remember he is unique among the English lords in Ireland in being styled king. He may even have encouraged that when alive

Please don't be sorry! I am delighted to chat about it. I don't think they were always foregone conclusions but seniority & wealth were big factors. There are recorded cases of buyer's remorse & of temporary depositions so the king did remain under pressure to keep up his end of the bargain

Apologies Ciarán, I misread your question. By my period the term airecht could mean King's entourage & included his underkings, so definitely still a considerable gathering but nearer your estimate. Voting rights not nec. limited to rígdamnai & multiple dynasties often retained a live claim

Interesting question! While we lack long dedicated accounts of any oenach, there are plenty of mentions in literature. There would be a lot of variation in numbers for a wide variety of reasons, but I think it's safe to assume most numbered in the 100s at least. Certainly more than one Derbfine
