No ! The UART1 and UART3 pins are used as ethernet pins.
The UART0 is available on WiFi headers for Bluetooth,
The UART2 is on the main header, as well as UART4 shared as SPI pins.
The schematic is useful to figure out such things ...
BTW, if you need more UARTs, it is better to attach some SC16IS752 to SPI port, it is a Dual Uart chip.
