You can also create a shared atlas texture for multiple skeletons by using the Spine Texture Packer separately, as described here (also packing by folder could perhaps be interesting):
Texture Packing - Spine User Guide: Using the Spine Texture Packer separately

You can also automate the export or packing process via the command line interface:
Export - Spine User Guide: Command line
For example, here is a script we use to export all the Spine example projects and to create texture atlases:
spine-runtimes/export.sh at 3.8

Thanks your help . I done it. 001.spine & 002.spine only export .json to unity , And new a TexturePacker.spine for create shared atals and just import .atlas .png to unity.

Glad it helped, thanks for getting back to us.
