Difference between fundamental and non-fundamental forces

Depends on what you mean by a "force".
If you mean the F in F=ma, then a force is a force; one is no more fundamental than another (except of course for fictional "pseudoforces" used to pretend that an accelerated reference frame isn't).
If you are talking about the "five Fundamental Forces" (Gravity, Weak (nuclear), Electromagnetic, Strong and "Superstrong"), they are figures of speech, not quite as figurative as "The Force" from Star Wars, but in the same league. All actual forces (F) arise from one or another of these "five Fundamental Forces". There are lots of difference actual forces (F) caused by "the Electromagnetic Force", from the electrostatic repulsion between a charged comb and a fleck of dandruff to the magnetic attraction of an industrial electromagnet for a chunk of iron. But "the Electromagnetic Force" is a metaphorical description for all interactions between masses mediated by the exchange of photons. Similarly for the others, except I'm not sure anyone does quantum field theory on gravity as an exchange of gravitons.
I hope that helps.
