According to the schematics, only the first four are user LEDs?

Cfr. Documentation/devicetree/bindings/leds/leds-gpio.yaml:
# The first form is preferred, but fall back to just 'led' anywhere in the
# node name to at least catch some child nodes.

Schematics say "run", so perhaps LED_FUNCTION_ACTIVITY?
color = <LED_COLOR_ID_GREEN>;
function = LED_FUNCTION_ACTIVITY;

Schematics say "error", so
color = <LED_COLOR_ID_RED>;
function = LED_FUNCTION_FAULT;

Schematics says Ether-Cat link-activity, so LED_FUNCTION_LAN?
color = <LED_COLOR_ID_GREEN>;
function = LED_FUNCTION_LAN;
function-enumerator = <0>;
