see peak location for 2-chloroethanol
DB-1 column should be similar in retention times given the diameter and phase thickness.

"these chromatogram is GC or GC-MS?"
GC
It is not the detector which determine RT, but carrier gas, its flow rate, column temperature, phase film type, its thickness, are the variables involved. There may be and there are variances between columns and even intracolumn which causes RT variations. You are expecting too much to predict with any accuracy the retention time of an analyte on a column.
best wishes
