Hi driansan,
1st pic I don't know. 2nd pic is a Beallara (maybe its Beall. Marfitch 'Howard's Dream', but not sure). 3rd one looks like Aranthera James Storei, an old vanda type hybrid. No 4, 5, 6, are dendrobium hybrids. no 7 looks like Aranda Majula, or something similar (Maroon Maggie?).. No 8 (which is shown without flowers) is cymbidium finlaysonianum, a local wild epiphyte. No 9 (pot with coconut husk) is doritis pulcherrima. No 10-15 don't know. No 16 (hanging clay pot) is coelogyne rochussenii. No 16 too small to make out what it is. No 17 is phalaenopsis bellina. No 18 is a catasetum species or hybrid (or cycnoches). Last 2 not sure..
