Very cool! Of this list, I would say peacocks and golden pheasants will probably be the only eggs you can find. eBay has some Emu eggs, but they're very expensive, and I cannot speak to the quality or reputation of the seller. Could be good or bad.
Regarding Parrots - there is nearly no chance that you will get your hands on any of those eggs. I have never even seen parrot eggs for sale, and if I did, I would be extremely skeptical of the products whereabouts. Reputable breeders who obtain their parrots from reliable sources (i.e. captive breeding) will NEVER let go of any eggs. A healthy Macaw sells for upwards of $1000, so the idea that the egg would be any cheaper is unlikely. Breeders will want a return on their investment, and creating a reliable breeding pair can cost 10,000 easily.
If you want an exotic bird, look into conure eggs. They are very pretty birds and their eggs are often available for breeding purposes (so I've heard).
Best of luck finding eggs! Do some searching on rare bird forums. You might come up with something. There are also exotic animals shows every now and then in various locations. These forums will tell you if there is an event in your area.
