Will- Your Abies balsamea 'Piccolo' looks okay to me. Abies fraseri 'Fastigiata Compacta' - this is likely the result of propagation of a side branch (tertiary, horizontal, rather than secondary vertical) and would be considered a cultivariant. It should develop a leader within a few years. Unknown fir: look up Abies forrestii Abies koreana 'Glauca' - could be 'Glauca' - do you have a spring/early summer photo, would be easier to make a guess. Abies koreana 'Green Compact' is likely the same as 'Compact Dwarf' Cheers- Brent

It's Turnera ulmifolia aka Yellow Alder, a tropical species that has naturalized in parts of Florida and Hawaii. Please note it is considered invasive in some areas. Here is a link that might be useful: Yellow Alder

Looks interesting, for a second I thought it might actually be some sort of cristate form conifer, but I think it's actually either cactus or succulent. Maybe Crassula Argentea "Coral" Rhipsalis cereuscula

It's a bit small to be sure but that's quite likely. the full pic is part of this presentation http://www.plyroom.com.au/products/peggy?variant=7110078788
