How to connect Arduino 5v pin with multiple things?
The simplest way is to just use a breadboard to connect your devices to your Arduino:





I can't read Chinese, so I can't check the specifications of these particular devices, but you need to be aware of the power limitations on your Arduino.

The maximum total current you can draw when the device is powered via external power supply is 1A for the Arduino Uno, 800mA for the Due and 500mA for the Nano. Check the specs for your board on the Arduino site. 

Arduino-compatible devices may vary - check the specs for the device you're usiing.



Note: If you're not powering your board via USB, the total 5V current limit coming out of the Arduino is limited by the voltage regulator on your particular board, and/or your input power supply (whichever provides less power).
