Those cute looking oncidium types are Tolumnia hybrids. You have to be very careful with them as they are very susceptible to attacks by mealy bugs and scales and die as a consequence, My friends and I have killed scores of them and have given up growing them , in spite of their beautiful blooms. That Phalaenopsis with the brown bars could be a hybrid of cornu-cervi x amboinensis; I have one that looks very similar. I don't think it's a fasciata. Sorry but I'm not a fan of pelorics. Those gerberas are lovely and that purplish blue water lily should brighten up your home. (not a lotus).
