The model has both a diffuse texture and vertex colors. The glTF material says they should be combined together.

The node graph for that looks like this (Shader Editor).

This node graph is too complex for the Collada exporter to understand though, that's why it doesn't see the textures. For Collada to understand it, you need to get rid of the "combine with vertex color" parts.

Do this for all the materials (the one on Mesh_2 has no texture so you can't do anything about that), then export to Collada and it should work. Be careful where you export, because the exporter will also create files named Image_0.png, etc in the same directory, and it will clobber any file with the same name that was already there.
Re-importing should get you

Since 2.8 Blender hasn't handled texture transparency in Collada (neither exporting nor importing), so this is the best you can do.
