No. The 2008 Olympics - is plural so the verb phrase - was held - should be plural.The 2008 Olympics were held in Beijing.
"How are you" is a correct sentence.
Yes, this sentence is correct.
You are palpitating. This is a correct sentence.
With the exception of not capitalizing the 'y' at the start of the sentence, it is a correct sentence.

justification by faith
I am not entirely sure if it is. . . I would reword it to "The party was at my friend's house last." No, "kept" is not the correct verb, "held" should be used.
That sentence is grammatically correct.
