I could be missing something here, but it seems all you need is to
just take the median of each 5 signal points at a time as you scan the
signal from left to right? I assume you are doing noise reduction that
is why you want a median filter.

So, for each signal point, the new filtered signal point will be the
median of the 5 data points centered at such a point (i.e you would
include the original point, and replace it by the 5 points median).
