For the two ethernet port, there is only one MDIO and MDCK signals. Can we share these signals for both MII and RGMII ?

MDIO (data, clock) signals are connected to Ethernet PHY devices. You can connect one MDIO interface to multiple Ethernet PHYs that have MDIO interfaces.

Thanks.

I would like mention, the AM335x MDIO and MDC I/O buffers are powered from the VDDSHV5 power domain which must operate at the same I/O voltage as all attached PHYs.
