As Bitcoin becomes slower each day in transaction confirmation time, other alternatives could prove to become useful for everyday transactions. Cryptocurrencies like Litecoin, Dogecoin, and even Ethereum have faster transaction confirmation time allowing you to send and receive coins at a hassle-free way.

Thus, among the wide variety of altcoins, many have block times which are near instantaneous. Based on these facts, which cryptocurrencies do you consider the fastest?

I would appreciate if you would list it or them here.

Dash has InstantSend, which is about 2 seconds and gives you 4 confirmations on a transaction.
It also has that transaction locked to prevent double-spending.

Why do you lock a transaction? Does the chain accept two of the same signatures? Stupid design.

InstantSend is realized off chain and then committed to the chain in the next block.
It's actually similar to what Lightning network should do on Bitcoin blockchain.
