One of the workshop gives the options to publish in university internal journal. Whether the paper will be accepted or not is not yet known for any workshop.
It is ok to submit it to 2 workshops: it is not ok to submit the same article to 2 or more journals or books (or a journal and a book), but this rule does not apply to conferences and workshops. On the other hand, it makes no sense to present the same paper at more than 2 events especially if the same people attend them as then you will not get many new comments.
