avrdude: Expected signature for ATmega32U4 is 1E 95 87
Double check chip, or use -F to override this check.
Wrong microcontroller found. Did you select the right board from the Tools > Board menu

It looks like you don't have an Arduino Leonardo. That signature is for a 328p based board. Did you select the correct COM port? Do you have other connected USB devices maybe?
