What counts as an alternate name? For instance Edinburgh (English) is also called Embra (Scots) and Dun Eideann (Gaelic). Do these count as different names? Or are they simply different versions of the same name? Both positions are arguable. Especially since all 3 of these languages are native to the UK
This isn't really correct. "Embra" is what we (I'm an Edinbugger myself) actually say, and "Scots" in a modern context is usually phonetic rendering of the heavily Scots-influened colloquial English. Actual Scots, the language that was fading with Burns, has always called it the etymologically correct "Edwin's Burgh": the King's Wall charter, which is the earliest source I can think of off the top of my head (1450), calls it "Edynburgh".
And of course the last time Gaelic was native to Edinburgh (plenty before the UK existed), I wouldn't be surprised if some obscure west Slavic language was still native to Berlin, so if we were to call that a viable alternative, almost everywhere has almost any viable alternative depending on who conquers of colonises it.
