A node can only have one Node Type. The node type will be "any" if you either:

•   do not specify a node type, or 
•   specify the node type as:  -DNodeType=Universal

 Agents can have multiple classifications.  Those classifications are used to choose which node or nodes to run on.

An active Agent Schedule for a node means Agents that match that node's type will run.

Not understanding what you mean by:

              Question: If an agent is stopped into one agent node, will master agent create data instance on that node too ? 

Do you mean the Agent Schedule is stopped for one particular node?

I would assume if an Agent Schedule was stopped it was stopped for a reason, Master Agent would not overwrite that schedule. 

The Master Agent would create an Agent Schedule if one was missing for a node.
