It seems you are right. I am at 159 now, less than 190.
Is there any way to check if I am at correct chain in future?
The best way to check is to delete all of your blockchain data except for your wallet file and rerun the node from scratch. The algorithm should automatically connect to the main chain that the majority is following. Early on when a blockchain just starts, it's common to have several forks until a consensus is achieved and a majority is following one chain.
The peers buta listed are offline because they are being banned immediately for breaking the reorg rule (i.e. they are more than 125 blocks off from the main chain).
