I always go with Lucas's and then use Lucas' as the singular possessive. As for plural Lucas possessive, I just try to avoid those scenarios. I wouldn't use Lucas's'. That just looks ridiculous.
Whilst it is more common to see it just with an apostrophe on the end, e.g. Lucas', it is actually more correct to write it with an extra s, e.g. Lucas's.
It is 'Lucas'. Joe Lucas, Nick Lucas, Kevin Lucas and Frankie Lucas.
