I have made many sentences using the structure 'be worth ....' Would you check the sentences and let me know ungrammatical esentences? Thank you.

Answer 1

11 is ungrammatical, by saying a person/object is worth something, we are putting a kind of value to that person/object. It is better to write 'he is worthy of praise' or 'he is worth praising'

Same reasoning applies to 13, where 12 is a more suitable form

Answer 2

Agree
