I read a lot thread that user connect n7 to ps3 controller, keyboard/mice, usb flash drive and etc.

I wonder how much current does the usb port support? So that I won't break my usb port. For example, I would like to connect a usb hub to n7. Then connect wired keyboard&mice and flash drive to usb hub. Does n7 support?

My friend try to connect external hdd to his tablet then the tablet turn off immediately. After that his tablet will turn off anytime and hard to turn on... So I scare to plug in device to n7 usb...port

I have a small external HD that I connect without any problems. And and external multi-card reader that I use for MMC, SD, mini-SD and Micro-SD cards. Both, of course, use power quicker than the internal SD. If you want to connect a USB hub to connect those other devices, my suggestion is to get a powered USB hub, rather than draw power from N7. Battery will last much longer as the devices will get their power from the hub not the tablet.
