If you are telling us to revise the sentence, one error is that there is a double negative. 'not' and 'un' would cancel each other, and the revised sentence 'I wouldn't say he's the nicest guy around, but I've seen him behave kindly before.'
Answer: "Two friends of mine are Kenji and Jose" is the grammatically correct sentence.
Explanation: In this sentence, "are" acts as the linking verb. It is a form of the linking verb "to be". However, "to be" has another form, "is". The type of verb to be used can usually be determined by how the sentence sounds.
The main way of deciding the verb to use is to relate it to the noun which is performing the action. If the noun itself is singular, "is" must be used whereas for plural nouns "are" is to be used.
When the form of verb is in accordance to the subject, it is called subject-verb agreement.
In the given sentence, the subjects are the two friends Kenji and Jose. Thus, the subject is plural. As a result, "are" is used and the correct sentence is "Two friends of mine are Kenji and Jose".
