If I were you, I would get 5 or 6 young angels, about 3" and watch them grow. You should get a pair that will live happily together when they mature and when young they prefer company. They will usually stick together for up to a year before they start to carve out territories.
I am guilty of keeping neons with angels but would be hesitant to recommend keeping them together once the angels are more than 6 months old. I know my neons are doing ok, but I cant speak for others that have different experiences.
The other fish you mention will live happily with angels but I prefer to keep fish native to each continent seperate as its easier than trying to find a happy medium with fish that have different preferences. In fact I am downright prejudiced against mixing them and would not have even asian plants in my south american tank if I could help it! most people are more reasonable though!
I can recommend peaceful dwarfs such as Apistogramma and Rams.

also, how many should i get if i want them to pair off, and would angel's survive with neon tetras, zebra danios, guppies and a silver sharks??? thanks
