My bet is you have a cheap fiancee, and the ring's copper that was plated with a white metal.

Why would you eat your finger? That is just weird. No you would not grow it back.
nothing, unless its not clean.
Where ever the tendon is located (example: finger) movement would not occur there (finger wouldn't be able to move)
That cannot happen as faeces would act as lubricant
Any finger you like :) it's not necessarily a huge commitment, not like marriage or engagement. It is not necessarily important to wear it on the finger you would for engagement or marriage. :)
You can wear a diamond ring on any of your fingers. If it is an engagement ring, you would wear it on your left ring finger, the finger next to the pinky.
Men do not traditionally wear engagement rings as they only wear wedding rings, it is only women that wear engagement rings. However, I would assume that this would be the ring finger, the same as women which is the left hand, next to the little finger.
* A size five is a small finger and a mid-sized diamond ring would be best. However, the sales clerk would know what would look the best on your girlfriend's finger size. The other solution is to take your girlfriend in and let her choose her own engagement ring as many couples do this and then you are sure she will like the ring. The selection she may choose may have a wedding band that fits with the engagement ring.
Once you're married, tradition dictates that your engagement band be moved back to the third finger on your left hand. When you do so, your wedding ring should remain closest to your heart (where your spouse placed it on your wedding day) and your engagement ring is placed next to the wedding ring.
Engagement rings are traditionally diamond so this would be the best stone to have set in a white gold ring for this purpose. If you would like to be less traditional then you could use ruby, diamond or sapphire, either alone or alongside diamond.
Your finger size may change over time and the wedding band or the engagement ring may also need to be resized.
* A boy does not receive an engagement ring like the girl; he would receive a wedding band when the couple get married. In the Western countries the wedding band is worn on the left hand (finger next to the little finger) and with European countries sometimes the wedding bands for both the bride and groom are worn on the right hand.

Copper was used as an alloy. Not good.
In the UK it is usual for the wedding ring to be placed on the finger first, followed by the engagement ring. This appears a little strange when one considers that the engagement ring is given first and is usually the more expensive of the two rings - although there is a trend here for diamond set wedding rings - and would be protected from loss if the wedding ring were to be worn after the engagement ring
In North America, it is not customary for the man to wear an engagement ring. However, if a couple decides to break from the norm, the ring is to be worn on the same finger as the female, that being the ring finger of the left hand. In some cultures and in certain parts of the world, the man and/or woman would wear the engagement ring on the ring finger of the right hand and then make the switch after they are officially married.
