Do you need two of these to make it work? Or do you need an internet connection?

You do not need two of these boards to work. For better accuracy, if you are not within a certain distance of a correction station, you may want to set up your own correction station with a 2nd GPS board. The board does not require an internet connection to communicate with your computer but you may want one for configuration and quick NMEA sentence viewing. But you can also connect it to a single board computer or microcontroller and add a screen if you prefer. There is a detailed hookup guide online for the board.

What is the lowest operating temperature ?

Unfortunately, we have not tested the operating temperatures of the board but the module is rated Operating temperature Topr -40 - 85 °C.

Besides the antenna connector type, is there any other difference between the gps-rtk-sma and the gps-rtk2?

The other main difference is that the GPS-RTK-SMA has a footprint so you can manually solder a connector for PPS to the board for your application. From the hookup guide: "Note: For those that need to connect a SMA connector to the PPS pin, the RTK-SMA includes a footprint so that you can manually solder the connector to the board for your application. The PPS output is helpful as a clock source correction when synchronizing equipment (not 1 Hz but in many MHz). The PPS output can be configured to output a very accurate clock which scientists use to correct less accurate, but much faster clocks. To configure, you can use the u-center to adjust The NEO-F9P's setting under View > Conviguration View > TP (TimePulse)."
