Please make the Subject better reflect the problem.
Just "help" is *not* useful.

This computes the average for days
(0) 120,125,133,138,143,148
(1) 121,126,134,139,144,149
:
(5) 124,129,137,142,147,152
============
If you want the five separate pentad averages,
the following untested code should do it
nlat = 94
mlon = 192
nPentad = 6
u = new ( (/nPentad,nlat,mlon/), "float", "No_FillValue")
nStrt = 120
nLast = 124
do n=0,nPentad-1
x = short2flt(f->lhtfl(nStrt:nLast,:,:))
u(n,:,:) = dim_avg_n(x, 0)
nStrt = nStrt+5
nLast = nLast+5
end do
u!0 = "time"
u!1 = "lat"
u!2 = "lon"
u&time = f->time(122:150:5) ; middle time of each pentad
u&lat = f->lat
u&lon = f->lon
printVarSummary(u)
