TubeAlongPath has been deprecated forever - PipeAlongPath replaces it.
It is 16 years old and expecting a free plugin to be updated is unrealistic.
I can't access any of them in your linked RAR file, but I see that ExtrudeAlongPath is 14 years old, and isn't even one of my plugins anymore, having been absorbed into my Extrude Toolset using some other name[s]...
These tools never worked on multiple paths and this late request is unlikely to be fruitful - 😞
