The small hexagonal one you can almost guarantee is a Sapphire, sapphire crystals are hex shaped usually and it's about the right colour. The long thin small one will need a better photo to give me a decent idea on what it is, could be a tiny dogtooth sapph but not likely as it's not quite the right shape, could be a beryl crystal but not likely either or a green quartz crystal.... maybe.
The clear ones are quartz and the reddish ones are Zircons and maybe a couple of garnets, Aussie zircon can be any colour from clear to any shade of red or brown.
