Yes, these warnings are important, and they are trying to tell you that by calling `include()` on the same file multiple times you are re-defining the same function over and over, which is at best wasteful and at worst can lead to problems like [Trouble importing a module that depends on another globally imported module](https://discourse.julialang.org/t/trouble-importing-a-module-that-depends-on-another-globally-imported-module/26482)
