Yes they are.
You can obtain a Gold Chao in Sonic Advance 1 and 2 by finding it in The Tiny Chao Garden, in the shop. There is a chance that there will be a Gold Chao. You can get other Jewel Chao, too. You can also transfer the Chao to Sonic Adventure 2: Battle by using the GBA link cable to the Gamecube or Wii. And also you can get one in Sonic Adventure DX but I'm not sure how...I don't own the game sorry. D: But I hope that helps!
