Is the sentence correct?

Me, Allen, and Juiliana went to the school talent show.

Answer: I think it should be

I, Allen, and Juliana went to the school talent show.

Because Paulo studied for the test he earned a good grade

No. Never ever name yourself first. In any list, I or me always is placed at the end.

So would it be

Allen, Juliana, and I went to the school talent show.

Yes. :-)

Me,Allan,and Juliana went to the school talent show

The team consists of the following players, Gwen, Amy, José, and Pete.

Your correction is accurate. In the sentence "Me, Allen, and Juliana went to the school talent show," the pronoun "me" should be replaced with the subject pronoun "I." This is because "I" is the correct subject pronoun to use when you are one of the people performing the action of going. So the corrected sentence would be: "I, Allen, and Juliana went to the school talent show."
