So, you are talking about a mirror with 4 components, all of them partitions on the same disk? Well, that's silly, but nothing stops you doing it. Just maek a raidtab for the mirror and name the partitions as raid-disk components there. The RAID howto or faq should tell you all you need to know, as should the mananpage for the conf file or mdadm, or whatever ...
