Just curious what thus is worth

Set of 6 chairs marked " Made in Italy" . 4 arm chairs and 2 side chairs.Looks to me as a cane chair furniture. made without and visible harware. 4 chairs in very good condition, 2 chairs need to replace seats .

John barleycorn royal doulton jug. Base of the jug has royal doulton mark as well as the number 48.

chinese vase owned by my great-grandmother that was turned into a vase. don't know anything about it's history except for that. I know things like this can range from basically worthless to pretty valuable so figured I'd try to learn more about it if I could. About 13.5 in tall and 5 in across for the vase part. Even just knowing what the signature (if that's what it is) part says would be super helpful

Its a cast iron fireplace insert with what looks to be a half naked angel and a cherub.

I have what I think is a hand painted Italian ceramic lion

This piece has 3 small chips on it as far as i can see (In pictures)

I've trawled the internet to try and get an idea of the value but can't quite find any that look the same i'd be grateful for any help, thanks
