I’m trying to create an experiment that measures different amounts of uv. My idea is to solder the vcc and gnd wires to the same pin, but then have each of the out pins connected to a different analog pin. Is this possible?
Welcome to the forum
I assume that you don't mean this literally and that you will, in fact, be using 2 pins !
What type of sensors are you planning to use ?

Can your board output enough current from the pin that you are using?
EDIT:
Oops I thought that you would connect them to a digital pin and turn it on and off.
Common supply and return you mean - seems fine to me.
That seems fine too 
I am using 3 Analog UV Light Sensor Breakout - GUVA-S12SD. I am trying to solder the wires that connect the to gnd pins of thug sensors to the same gnd pin of the microcontroller, and the vcc pins of the uv sensors to the same 5v pin of the arduino nano microcontroller.
Should be ok.
Operating voltage of sensors?
