We report on four Σ's and three Λ's, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave (1/2)+ resonances found by solving the Faddeev equations in the coupled channel approach, which can be associated to the existing S = -1, JP=1/2+ low lying baryon resonances. On the other hand we also report on a new, hidden strangeness N∗ state, mostly made of KK¯N, with mass around 1920 MeV, which we think could be responsible for the peak seen in the γp→K+Λ around this energy. Finally we address a very novel topic in which we show how few body systems of several ρ mesons can be produced, with their spins aligned up to J=6, and how these states found theoretically can be associated to several known mesons with spins J=2,3,4,5,6.
