My additions to these sentences are the following:
1. I hate being lost in a desert!-exclamatory sentence.
2. I want water!- exclamatory sentence.
3. Yippee! It's going to rain.-interjection.
4. Oh, no! It's a flash flood!- interjection.
5. Get to high ground!- imperative sentence.
6. Hurry! The water is rising quickly!- interjection.

8. What a frightening sight that is!- exclamatory sentence.
9. Whew! Let's go home!- interjection.
10. I can't wait to tell my friends!- exclamatory sentence.

It's impossible to tell out of context if all of these sentences need exclamation marks.

What do you mean?

If a person were actually lost in a desert, then an exclamation point would be appropriate. However, if the sentence were

I hate being lost in a desert, even though I quickly found my way home.
