How to link .FBX animations on a skin to animate a rig

I’ve bought a model that comes animated, but it only came in 3Ds Max which I cannot install. I received an update from the designer in the form of a folder with .FBX files in where I have one skin (The model with a skeleton) and then a bunch of .FBX files that seem to be animations of that skeleton but I don’t know how to link them to the model.

The model is animated in a resting state (Moves a bit).

It would help me a lot if someone could point me to a tutorial that will help me get this because I want to learn it, but I’ve got little time to do so as I have a deadline to reach and my fulltime job isn’t giving me enough free time to learn everything from A-Z so I’m trying to do things as efficiently as possible.
