All & total

Hi,
How could we say if we say like below, which is correct?
1. All sites are completed.
2. All site are completed.
3. Total sites are completed.
4. Total site are completed.
5. All site is completed.
6. Total site is completed.
Or does it have different meaning?
Let's say,
No of 10 separate construction sites =All, Total.

Thanks.
