It would not be possible for us to work on all of these together. Please ask one question in a single thread. You can post the remaining in separate threads.
 

1. Both also and too mean the same and they can be used interchangeably. However, the placement of the words is different. Also is used in between a sentence whereas too is used at the end of a sentence. For example:

I have also been to Hong Kong.

I have been to Hong Kong, too.
