The WN (Web Novel) was created first and is basically an unedited "first draft" version that can be read for free.

Then came along the LN (Light Novel) which is commercially sold as a book (and e-book) and is essentially the "canon version" that went through a proper editing process.

Then came the manga and anime which are both adaptations of the LN.

Finally there are the spin-off manga. The one called something like "strolling through the monster nation" is a spin-off of the LN, while Slime Diaries and Trinity of th Monster Nation are both spin-offs of the manga. Other than those 3 spin-offs I just mentioned, all the other remaining spin-offs are "Alternate Universe" types which have no relation to the main story.
