There's no clear answer to your questions. It depends on the amount and kind of data that you ingest, query, store.
What for sure can be said: One Elasticsearch instance should not have more than 30GB of heap.
Elastic provides a pretty good starting point regarding the sizing:
General: https://www.elastic.co/blog/found-sizing-elasticsearch
Heap sizing: https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html
I would not start with nodes lower than 4GB of RAM. So 2GB for the heap and the rest for the filesystem cache.
