Setting up groups

I guess we can only measure the length of a single trace segment at a time by selecting the option Display --- Measure and then selecting the two end points of the particular trace...

Why don't you go for propagation delay\Relative propagation delay CM settings. Here you can create groups or classes as you requested.

Maybe I wasn't clear. Here is what I am trying to do. I have several groups of about 20-30 nets each that need to be within 5mm and 25 mm of each other with specific trace width and space. I am pretty sure they are all correct since they were done the hard way in Orcad before I translated the board. However, since there were a few hiccups in the translation and I had to redo some connections I would like to double check all of these signals to make sure. I would like to do this via the program and not by querying lengths or a report. Thanks

Let me clarify. I meant that they need to be within the 5mm or 25mm of each other in length.

Use the constraint manager to create a match group for each group of nets. then assign the relative propagation delay property with the values you need. Be aware that the tolerance field is + or - from the target. Once this property is set, Allegro will generate a DRC error for any nets that are out of tolerance.
