When using an appositive or interrupting information, it is most often separated by commas. Therefore, sentence one is not correct. To correctly use dashes, one should use them to add emphasis for an interruption or a change of thought. That means the second sentence (after cramming...) is correct. In the 4th and 5th sentences, the commas are misplaced. The third sentence used the commas correctly to separate the combining sentences with the coordinating conjunction (but) as well as the appositive, which starts with 'who'. Added note: appositives start with: who, which, and that.
