its best not to right away...
Yes it is very normal if you play with it a lot, tongue rings will stretch no matter what because when you eat a lot of people tend to bite it, I bite mine all the time when I am eating. But that only stretches it a little, if you constantly play with your tongue ring, like I do you will stretch the hole, but it's not noticeable. If you were to actually try and gage your tongue piercing then it'd be noticeable, but if you're not gaging it and only playing with it, expect it to stretch, nothing bad will happen.
if your tongue is between your front teeth when you suck it, you get an open bite. your front teeth can also stick out. i suck my tongue too but instead of it between my teeth, i fold my tongue in half and then suck it. that caused me to have an overbite because somehow in folding my tongue and sucking it, it caused my lower jaw to go in hence my overbite.
To change a tongue ring, start by washing your hands with soap and water. Gently unscrew the ball at the bottom of the current tongue ring using clean hands or latex gloves. Slide out the old tongue ring and carefully insert the new one, then screw the ball back on tightly.

Go to your piercer when the swelling goes down and they'll change it if its ready.
Yes, you can get a snake bite ring on the first placement
Nothing. You don't have to worry about biting the tongue ring if the barbell isn't too long for your mouth & if you don't use it to click your teeth.
No one understands your ungrammatical/incomplete sentence. Also, there really is no such thing as a tongue ring, though there theoretically could be. I believe you mean a tongue STUD.
