The K64F has 5 UARTs according to its decription, I don't think any will have more than that. Then depending on your requirements (speed of UART, other code running), you can either make software UARTs for the remaining ones, or use SPI<>UART bridge ICs.

Thank you for your answer. Do you know how to use mbed compiler on non mbed board such as stm32f429 discovery which has 8 uarts

The MAX14830 is a quad serial UART. Two of those would get you 8 UARTs from an SPI port.
