Certainly! I'll check the meanings of these phrasal verbs for you. Here are their definitions:

1. "Come around" means to change one's opinion or attitude about something or someone over time. In this context, it means the speaker started disliking their classmates but eventually began to think of them as not being so bad.

2. "Drop in on" means to visit someone briefly and without prior notice. In this case, the speaker is asking the person addressed to visit them after school so they can have a conversation.

3. "Fall through" means that a plan or arrangement fails to happen or is canceled, usually due to unforeseen circumstances. Here, bad weather caused the speaker's plan to go to the mountains to not happen.

4. "Turn out" means to attend or be present at an event or gathering. In this sentence, it means that thousands of people attended the concert.

5. "Turn over" means to rotate or flip something to its other side or surface. The sentence suggests that if you turn over the photocopy, you will find the solutions to your test on the other side.

6. "Turn out" can also mean to be discovered or revealed to be a certain way or have a certain outcome. In this case, the idea turned out to be incorrect.

As for your last request, an example of "turn out" meaning "to empty" is: "I turned out my pockets and found some loose change." Here, "turn out" refers to emptying the contents of one's pockets.

I hope these explanations are helpful!
