Can I launch URLs from command line in Windows?

What's "launch" in this context? You can start http://www.foo.bar/ or the like, your default browser will come up and visit that URL -- is that what you mean?

"you can run this below command and it will redirect to google chrome browser

C:\>start 'http://www.google.com'"

"You can use this in Powershell:
Start-Process ""URL"""

"From C# code you could just run this (cmd-start equivalent):

Process.Start(""http://stackoverflow.com"");

You've launched your url from a command-line directly (i.e. without running another program first)."
