What is the difference between "eldest" and "oldest"?

"Oldest" is more general and can describe people, animals, or objects in any context, including families, so "eldest" is really a narrower, more formal option within that overlap.
Can you use "eldest" for only two siblings, or does it need three or more?
Strictly, comparative forms like "older" are used for exactly two people, while superlatives like "eldest" are meant for three or more. In everyday speech, however, many people use "eldest" even with just two siblings, and this usage is widely accepted despite the formal rule.
Is "eldest" only used for people?
Yes, "eldest" is essentially restricted to people, particularly within family relationships such as children or siblings. For non-human things, such as buildings or trees, "oldest" is the natural and correct choice.
