Yes, the results should be presented here.
The results will be presented by the students participating in your X-Student Research Group. Ideally, of course, you will be there as well.
Usually, the results are presented in the form of short talks or as a poster presentation. However, other forms are also conceivable (e.g. exhibitions, video or audio formats), but must then be discussed with the program committee in advance.
The conference is held once a year in September.
That is not a problem. You can present interim results or, if you wish, describe initial ideas for your project.
