HI Fran Gonzalez
There are a couple of ways to do that…
You can Save your “Animation group” into the “My Objects” area of your Carrara browser,. Then drag it back into your working scene to create a new figure,. do that as many times as you need, then place the animated figures where you need them.
You could use a Surface Replicator to create and distribute the objects (as instances) on the figures head.
You can also use an option /button within the “Surface Replicator” to (Create) which creates real “copies” of the replicated object, instead of instances.
When you “create” real instances,.. All the instances will be placed into a group called “replicator converted” (you can ungroup these if you want)
Each instance will have the same NLA tracks and NLA clips as the original model.
you can select each model, and go to the NLA options and adjust the speed of each animation clip so that there are some models moving faster or slower than the others.
Hope it helps
Also,... there’s a Carrara discussion forum here, where you’ll often get a faster answer to any Carrara issues.
