Hi there. The temperature range for this unit is 46-55 F. This was specifically made for wine, so if your other drinks are long enough to fit on the grooved metal wires without falling through, then yes this cooler will accommodate other drinks. Here's a similar wine cooler that is specifically made to store wine on side, and soda/beer on the other:

I hope this answers your question. Feel free to follow up with any additional questions.

can this be used under a counter?

It would depend on how much space there will be around the wine fridge. The main concern is proper ventilation. The best way to tell if a wine fridge is built-in friendly is if the vents are on the front of the unit rather than the rear/sides.
