No, do them all at once with Cuffdiff:
(a) set 'Perform Replicate Analysis' to 'Yes';
(b) create 5 replicate conditions, one for each time point;
(c) add your replicates for each time point.
There's a Cuffdiff flag to do time series analysis, but it isn't implemented
yet in Galaxy, so you'll get pairwise comparisons for all conditions. You can
use the filtering tool to reduce Cuffdiff outputs to only the timepoint

Use the process I described above to do all pairwise comparisons in one run.
