They're for Garry's Mod, though. You'll have to do some Googling to find some tools to export them into a format Alice can use, or at least one the converter tools the threads mention can use.
Looks like the most likely option would be mdl->3ds->ase.
3ds to ASE tool (Biturn) is here:

You'll need to find a tool to get the objects from mdl to 3ds.
Or you could find different models in 3ds format already. Google five nights at freddy's 3ds model and see what you get.
Game development is a lot of work. You won't get far if you get discouraged by something as simple as this.
