Hello, i have 4 sensors. Three of them have a simple UART interface and the last one has an I2C interface. My question, is it possible to connect all four sensors to mbed at the same time and readout the data?

From the diagram it looks not very straightforward - you have 3 UARTs and 2 I2C, but those are shared with UARTs, so looks like only 2 UARTs + 1 I2C is possible without additional, probably not easy programming...

Check out this forum, I needed 4 UARTs, used the alternative mbed pinout and a max spi to uart chip.
