I guess Mars meant converting a contour lines of 10 metre intervals to 5
metre.
Best to do it using GRASS (plugin). Here is a nice Wiki page:
http://grass.osgeo.org/wiki/Contour_lines_to_DEM
Once you have it as DEM (i.e. raster) you can use r.contour in GRASS or
Contour tool under GDAL in QGIS (Raster > Contour) to convert it to 5
metre contour vector.
