Basic UART and SPI are included for free with Quartus. There are free I2C cores at opencores.org (http://opencores.org) along with a lot of other free cores.

Only as SOPC components (NIOS II peripherals). Although you are basically able to extract the code and use it for native HDL designs, it's far from being convenient. Opencores is always a place to look for, but the UART and SPI IP tends to be more complex then needed for basic functionality. Simple UART designs have been published at Altera forum before.  

 

SPI in a native HDL design isn't much more than a shift register. Data formats and clock speeds as well as parallel data connectivity are changing for each implementation, so it's probably best to write it from the scratch, tailored for the respective application.
