Please let me all these Questions and Answers are correct or not and also usage of grammer i will be very thankful to you…waiting for reply as soon as possible.[/u]

Your questions and answers are correct. (In this case the answers are the questions).

Although you have used the correct contraction ‘where’re’ I think most people would actually write ‘where are’ out in full.

in the present continuous ,we usually face some problems and differences with the simple future due to the point of the future . so the question is that how I can distinguish them when using the future ?!
