I'm not sure on common names, but I think u got Acanthoscurria jurencola, and Nhandu Tripepii.
Both are fast growing and easy to keep. They don't need heat pad for the winter as they both are pretty hardy spiders. You can offer them large prey as they both have a big appetite.
Maybe post some pics of them, will help us be able to identify them and tell u more about them.

allowed to give there own opinion.
