No, not quite sun conures are a little larger than green cheek conures.
There is a huge difference in size. Sun conures and Green Cheek Conures are both small parrots, only slightly bigger than parakeets. An Amazon is a medium sized bird and will most likely kill the smaller Conures.
Conures are not one specific breed of bird. Conures is used to describe either large parakeets or small parrots. There are over forty different species that are described as conures. Conure is not a scientific name, therefore it does not have a specific definition.
Some Conures when you buy them do come in pairs but others they come individually.
yes they do
A conures life span is somewhere between 10-25 years depending on how well they are treated. Males tend to live longer from not having the stress that the hormones cause in females.

Does the male in any specie lay eggs? I don't think so!

They can be taught to talk, yes.
Pineapple conures and crimson-bellied conures belong to different species within the conure family, and typically, different species do not breed successfully. While they may display mating behaviors, viable offspring are unlikely due to genetic differences. Hybridization is more common among closely related species, so these two are not likely to produce fertile hybrids. Always consider the health and well-being of the birds when thinking about breeding.
