I believe the first one is too broad.
Come of age means growing up. When you have more responsibilities, when you're moving from childhood to adulthood and understand more things. When you are changing but not only physically, also mentally. When you are becoming more MATURE.
The second conflict is that Jacob must decide whether he should stay with Miss Peregrine and his new friends in the loop hole, or stay in the present-day with his family. He knows that if he stays with his family he will live in fear for the rest of his life. He also knows that he may end up like his grandfather if he continues in the real world. However, he also knows that he would miss his family if he went to live with Miss Peregrine. But, he can not bear to think about life without Emma. Jacob must make a decision that will have a huge impact on his life. This conflict is man v. self.
