worthy has 2 distinct synonyms spread across 1 of its 4 senses. Each sense below keeps its own list, because a synonym belongs to a meaning and not to a word: swapping one sense's substitute into another sense's sentence is how a thesaurus makes writing worse. Its one recorded opposite is unworthy.

having worth or merit or value; being honorable or admirable
“a worthy fellow”
an important, honorable person (word is often used humorously)
“he told his story to some conservative worthies”
