Hi

[rebeccaJones]

my name is Rebecca, I own samsung galaxy 3 on android 2.2.

I want to know if I can upgrade android version and whether my phone will support it.

You need to have the latest version of Samsung Kies installed on your computer.
Download it from here:Mobile Phone's Software&Manual SAMSUNG

Let it run and see if it needs an update. Then connect your phone via USB cable and wait for it to connect. If there is an update available, it will automatically be detected.
