Bottom line piercing the cartilage is always problematic with piercing guns so I would tell you to see a real professional body piercer and get the piercing done with the basic jewellery to start then consider changing it once you have crossed the initial healing period.
If its a healed lobe piercing, it probably can. 16ga is .2mm bigger than 18ga. If its cartilage, you may have to wait till its older to try out bigger jewelry. It really helps to try and put it in after a hot shower and use extra virgin olive oil, vitamin E oil, or jojoba as a lubricant.

Nobody makes a bullet that small. The smallest bullets are at least 4mm in diameter.
2mm 2mm
6mm is thicker than 2mm.
It depends how long you were at 14ga before you went to 12ga. But that's still a pretty small size so it'll probably close up well. Even if it doesn't go completely back to 18ga, it wont be noticeable.

2 is smaller than 3, so 2mm is smaller than 3mm.
kidney stones come in all shapes and sizes. they are usually rounded and bumpy. not smooth, obviously. 2mm is roughly about the size of the head of a pin head.
10cm / 2mm = 100mm / 2mm = 50/1
It is 7 mm - 2 mm = 5 mm.
