Is Arduino uno SPI comunication can be also master and slave in the same time?
You can have several devices on an SPI bus. Each must have a chip select. The Arduino SS pin (Uno pin 10) is often used for chip select. Chip select pins should then be in output mode. 

Connect the sensor and display to the SPI bus (MOSI, MISO, SCK) and use a chip select pin for each. 

A driver (library) for a device connect to the SPI bus will typically assert the chip select pin and transfer commands and data. The SPI transfer is both read and write at the same time.
