Could you please help me correct these sentence I'm having trouble correcting?

1 You're not allowed to rent the place for so much.
2 Wait for her to get back from her weekend before telling her the bad news.
3 I won't be able to get there before 5 pm.
4 The people who were on the bus when I got on were most likely coming from the rugby match which took place downtown.
5 We were on two different flights but on the plane at the same time/I was on the plane while you were too.
6 These shoes make her feet look feminine.
7 The exit is on the other side of the platform.
8 We must have walked too far up the street that we missed it.
9 She has too big a gap between her front teeth.
10 I'm not the least (bit) upset about what she said.

Thank you
