• 1 67 8 10 5 (doesn't specify where)
• Yes (doesn't specify where)
• Gives you exact coordinates to a town called Troy in the US that existed during the Greek civil war of the 1950s

Can't help you with the first two, but the third is Wilusa, and the problem is more with the when than where.

Homer fucked up and combined the Mycenaean conquest of Anatolia in the 14th century BCE (the catalog of ships and Helen parts) with the sea peoples retaking the city from the Hittites in the early 12th century BCE after the Hittites took it (presumably in their pursuit of Piyama-Radu) and Tudhaliya IV re-installed their own loyal representative in the late 13th century.

This ended up completely messing up Greek timelines, btw, with them thinking the Argonauts (the loose tales of the sea peoples period) was before the Trojan War (it straddled the 12th century capture of Troy but was well after the Mycenaeans), or how Perseus is his own grandfather depending on the lineage being followed.
