I think your answers are correct; however, it really bothers me that you don't start sentences with a capital letter, don't end sentences with a period, and use i instead of I. I know it is a time saver, but honestly, pushing the caps button and not pushing the caps button may save half of a second. Perhaps even a full second but that's no large savings, especially, when doing so makes your posts so much easier to read.
Yes! Both are right!
Great! Job Good job
