"Vnodes on different data nodes can form a virtual node group to ensure the high availability of the system. The virtual node group is managed using RAFT protocol. "

Hence a vgroup is a group of VNodes with the same number

like vgroup2: Vnode2,vnode2,vnode2

am I right?

yes you are correct .

In TDengine base,vgroup does be a group of VNodes with the same number.

If replica one , then vnode2

If replica three ,then vnode2 ,vnode2,vnode 2

In TDengine 2.0 , we support 2 replication, but in TDengine 3.0 ,we don't support it anymore .

we use three replication with raft to make sure consistency .
