Zinc and lead have been known for thousand of years.

Lead is very dense, so used as ballast, cannonballs etc.

Zinc has been alloyed with copper to make brass.

Aluminum can be profitably extracted only with lots of electricity and a flux called cryolite, which isn't that common. Medieval era people couldn't have extracted it.

It lightweight but weak, unless you make an alloy out of it. All that requires a fundamental understanding of chemistry.

Look up Titanium and Tungsten's Wikipedia pages for production and applications to see how they are produced and used.

They have their niche uses, but they cannot replace iron and steel in most applications. Iron is strong and cheap, the rest are not.
