"non-fresh" is because of that "events" counter in superblock of sda1 is at least 2 lesser that others.

here "dirty" results from system crash while writing data to the raid.
using "--froce" param with mdadm could start the raid, 
or md-mod has a param "start_dirty_degraded", if you load it with "start_dirty_degraded" set to 1, 
your raid5 could be started.
I think no more data would lose or corrupt if only doing raid start operation, but you should first get more 
replies and suggestion :)
