Not too bad on the ID's
First Picture,
Left: Tricho Hybrid Pachanoi x Bridgesii
Right: Tricho Peruvianus 'Icaro'. An awesome plant very blue and a big fat plant that puts out serious growth.
Second Picture,
Front: Trichocereus Thelogonus
Middle Left: Pachycereus (Lophocereus) Schotii Monstrose
Middle Right: Trichocereus from KK338 seed but who knows what it is given Karel Knize's poor record keeping etc.
Rear: Now this an interesting plant ! Isolatocereus Dumortieri, still a cutting but will grow into a massive tree like plant in a few years
