Welcome to the Forums, umer! This particular exercise is a good one, in that it asks to identify the use of words that can have various functions. Since this is your first post, you probably are not aware of the fact that we do not do students' homework assignments for them. Rather, we prefer that you give it a try first and let us help you if you have particular problems. That process is really much more educating that our providing you with the answers.
