Questions on lenses

First check that they are Pentax mount - the Yashica almost certainly is not (I don't think Yashica ever made PK mount lenses)
Secondly as 'thrid party' manual lenses they are not worth much. The Sigma would be lucky to fetch a tenner on ebay. The Vivitar 200mm might do a bit better.
3xconverters are not a great idea - they amplify any shortcomings in the lens to much and mean you lose 3 stops of light (so the 200/3.5 would be come a rather poor 600/10.5)

If I owned them, I would want to get rid of them, too.

I was offered these lenses, they are all manual lenses which is not a problem. The owner wants to get rid of them so I might get them for a good price.
