Hi, I wonder if there is a way to increase the JVM Heap size of a node. I am curretly using cloud hosted Elasticsearch, and just want to increase 200mb of the heap **Max** size for one of my instance

No, that is as far as I know not possible.

To be precise, it's not possible to increase the JVM heap size _of a single node by 200MB_ but that's not normally something you'd want to do anyway. Instead, you should scale up the whole cluster (or at least the relevant data tier) which increases the heap size of all the nodes.
