Can i use an old docking station speaker to play music
And what does the docking station do? How does it work?
Why do you think it would not work?
We cannot tell you whether something works or not, if we know nothing about it.
In general a speaker or dock with a lightning connector should work with an iPhone 8. But without any more specifics , its hard to say for sure.
