1 - It's a good exclamation! Put an exclamation mark at the end. "Guys" is not generally considered rude; it's just casual. It's an indication of familiarity with whomever you're speaking to.
2 - 4 -- All are fine and all mean the same thing.
8, 9, and 11 read somewhat correctly. I hear different people (in life and on TV and radio) use slightly different expressions. Here are what I hear most:
June first, two thousand two
June first, two thousand and two
June first, twenty o two
1. Cheer up, guys.
(What other expressions can we use instead of 'guys'? Is 'guys' a rude expression?)
2. Can you make it at ten?
3. Can you arrive at ten?
4. Can you meet at ten?
(Does #2 mean #3 or #4?)
5. Finally I made it.
6. Finally I succeeded in it.
(Does #5 mean #6?)

(Which ones are read correctly?)

5 and 6 are essentially the same, achieving a goal. However, without a context to clarify it, 5 might mean that you finally constructed a physical object.
