How many milliamperes does a GPIO pin of the MCU draw minimum and maximum? Where can I look in the datasheet.

The electrical characteristics section of the data sheet tends to have all that info

It's more complex than on the simpler chips.
15mA max on any four pins.
25mA max on a group of 8.

As jeremiah said above, you need to read the datasheet Electrical Characteristics section (use the datasheet index).

Absolute Maximum Ratings
Ambient temperature under bias..........-40°C to +125°C
Storage temperature ...................... -65°C to +150°C
Voltage on V DD with respect to V SS -0.3V to +4.0V
Voltage on any pin that is not 5V tolerant with respect to V SS(3)... -0.3V to (VDD + 0.3V)
Voltage on any 5V tolerant pin with respect to V SS when VDD  3.0V(3). ... -0.3V to +5.5V
Voltage on any 5V tolerant pin with respect to Vss when V DD < 3.0V(3) .... -0.3V to +3.6V
Maximum current out of VSS pin .........................................300 mA
Maximum current into V DD ................................................300 mA
Maximum current sunk/sourced by any 4x I/O ........................15 mA
Maximum current sunk/sourced by any 8x I/O pin ...................25 mA
Maximum current sunk by a group of I/Os between two VSS pins(4)...200 mA
Maximum current sourced by a group of I/Os between two VDD pins(4) ....200 mA
