Try in say, F1:

=SUBSTITUTE(TRIM(A1&" "&B1&" "&C1&" "&D1&" "&E1)," ",", ")

Copy F1 down

The above essentially uses TRIM to remove any extraneous "in-between" spaces
from the concat string first, then SUBSTITUTE will replace all the single
spaces: " " in between words with a comma-space: ", " to give the desired
result

When using concatenate if I have cells that are empty in
that row how can I disregard including the empty cell,
without typing function in manually for each row ?

Example:
Col 1 Col 2 Col 3 Col 4 Col 5
Dan Dave Paul Sue

Function I use is
=CONCATENATE(A1,",",B1,",",C1,",",E1,",",)
Results I receive a Dan,,Dave,Paul, Sue
Like to see: Dan, Dave, Paul, Sue
