Do all particles like pions, kaons, sigma, tau, whatever, all carry the elementary charge +-e ?

If the quark inner structure has total electric charge "e" in absolute value,then,yes...

Search for their quark structure.It's the only way to determine their electric charge.

Well, the tau is a lepton... with no inner quark structure, with a charge (like all leptons, besides for all the neutrinos partners) of 1-.

pions are found with three possible charges: +1, 0, -1. Also there are baryons with charges of 2 or 3.

Really? Which? I only know of protons and neutrons.

I vaguely remember in the $\Delta$ decaplet this object
$$\Delta^{++}$$

So that's an example.You can search for more.

Wow thanks, I searched and came up with many more, there are your deltas, as quasar said the sigmas, lambda, Xi Cascades etc.
