Do we need to connect the hdmi cable from the raspberry pi to the computer after copying noobs to the sd card , or only usb port is enough? I am not getting any sign in my laptop after connecting my raspberry pi. the red led glows.

Laptops don't usually let you use their monitor as an external display (such as for your pi), the HDMI there is output only. To see the pi's graphical output, plug it into a tv or other external monitor such as the one linked in this class.

Your computer's USB port may not provide enough current for the pi (max 500mA), so you should be using a higher capacity wall adapter or battery pack (at least 1000mA).
