What should be the ideal memory setting for 16GB elasticsearch nodes? We don't have the servers with 64GB to set the memory to less than 50%, say 30GB. Whether 8GB to 12GB is fine?

Whether it is applicable for all types of nodes? Master Node, Hot and Warm Nodes, Coordinating nodes?

Applicable for data nodes. You can increase that ratio for master nodes and coordinating only nodes.
