Unfortunately, the current version of Elements does not accommodate changing time-steps from within the editor. However, if the data from your EPW file is already in 5 minute increments, Elements will read that in correctly and respect that 5 min interval. Therefore, if you can find an existing epw file that has 5 minute increments, the easiest work-around would be to load that file and then past your new data.
If you don't have a pre-existing *.epw file at 5 minute increments, it is possible to edit the text of an *.epw file using Excel (load it as a comma delimited file and save as a CSV and rename the extension -- note: take care with how date formats are written out). Doing that, you could add the 5 min increment steps manually. However, that process is very involved and error prone so I cannot recommend it unless you feel comfortable with text editors and the *.epw file format.
Unfortunately, I'm unfamiliar with the .mos format for weather data. You should be able to process .csv weather data using the EnergyPlus Weather Converter but I'm less familiar with that process and will defer to others to provide a more substantive answer.
All the best.
