Arzakon isn't a Shandalarian name, though, as Arzakon was a planeswalker not native to Shandalar. There's Azar, though, which sounds somewhat similar. Sarlena, paladin of the Northern Verge also comes to mind. The wiki gives the names of the five guildlords as Alsadim K'mer, Starcryst, Lichlord Skavius Slan, Kzzy'n, and Morgane, the Great Druid. Then there's this random bloke who gets killed by Liliana in one of the webcomics, but I can't give you his name because the **** comic is buried god knows where.
Edit: Basically what Helio said, and keep in mind that different names come from different centuries or even millenia as well as from different races and cultures.

So... pretty basic fantasy names, I'd say. More interesting, the comic also makes a huge point about Shandalar's mana being special. So abundant that even lowly commoners can use it, but weird, and possibly alive somehow, so that Leshrac and Tevesh Szat can't use it. Lim-Dûl can though. That all seems to have fallen by the wayside, though since the comic is a bit of a mess, never explaining what's up with the mana, why Lim-Dûl can use it or what people's actual plans are, it's not surprising that a lot of it was ignored by later writers.
Which, to no surprise, contradicts earlier material published, admittedly obscure material, but all the same.
The vec, dal, and kor were all just from Dominaria in earlier versions.
Doug really hates the old canon, does he not?
I've just gone through all the Rath era article of The Duelist, Rath and Storm and the Rath Cycle art book for my blog. They say Rath is a parasitic plane of Dominaria and only mention it crossing over with that plane, not with any others. They also only mention species taken from Dominaria (The Vec, Dal, Soltari, Thalakos, Dauthi, Skyshroud Elves and Rootwater Merfolk) or those "probably" created by Volrath's experiments (Slivers, Spikes, Licids). Reading it all in one go it seems abundantly clear that the intention was that everything on Rath came from Dominaria.
However... it is never explicitly stated that Rath didn't also take creatures from other planes, the Kor are never explicitly mentioned as being from Domnaria and the Slivers are never explicitly mentioned as being Volrath's creations. So bizarrely, and perhaps by accident, the recent revelations about Slivers and Kor did not contradict anything concrete and can easily be reconciled with the Rath era lore by just saying "oh, the Phyrexians also brought stuff from other planes to Rath".
The amount of lore from Tempest block that gets contradicted by Urza's block, now there's a huge ret-conny mess!
