I need a 5V power to supply to a circuit. I wonder, in case I supply 5v by the micro USB if I can use the pin left of the micro usb, right to the gnd between the 5V in and 3V in pins.
It seems that, that pin has a 5 V level ????? That pin is not explained in the specification sheet I have

If you look on the pinout card that came with your Teensy LC, 3.x, or 4.0, you will see on the back of the pinout card:

Cut to separate VIN from VUSB if using battery or external power

That points to a solder tab that if cut, severs the connection between USB power and the Teensy. The inner pin (VUSB) is connected directly to the USB power and the outer pin (VIN) is where the power comes from. Normally they are connected, but if you cut the pad, you will need to apply 5v directly to VIN.

Here is the online version of the pinout card:
