I want to buy usb hub for arduino leonardo. I need 5 or more arduino on one usb port. I need this to handle switches, leds.. Will it work?
USB 2.0 can give you 500mA maximum. I cannot find exactly how much Leonard consumes but I think it should be enough.
Will it work?
What is required for you to say 'it works'?
Each Leonardo will need it's own COM port to allow the PC to talk to it.
I think you're after something like this
Amazon.com?
Currently in the Device Manager on a Windows 10 System I have two Arduino Uno and one Arduino Mega and I could add another if I wanted to.
That said I noticed I can only open a single instance of the serial monitor to view a single port. I can use other serial port monitoring like Tera Term or even the old Windows Hyper Terminal.
As I add devices the Device Manager just assigns new com port numbers. Adding additional devices using a 4 port or more USB hub should work just fine. Look to buy a powered hub.

Thanks for help. I will try to buy something good. 
You really need to explain why you are using more than one Arduino.

That is a single instance in a single window. If you open a new window, you can have the serial monitor running in that new window. I have successfully done that to test two Nanos at the same time. Works.

Good to know and thanks Paul. I did notice I can run multiple instances of Tera Term at once looking at the different com ports.

Yes, the Arduino IDE and monitor work exactly the same way.
