Some piercings can be done with Bioplast or PTFE, you would be wise to ask your local professional body piercer if they stock or carry either material that would be acceptable for your requested piercing.

No. It's just steel or plastic in your mouth.
Not plastic/acrylic, its too porous for a new piercing. You can probably get glass though. Glass at smaller sizes is very fragile though. Bioplast is another option but its not as clear as glass.

No. Plastic can't be autoclaved, it will melt. Which means that it can't be sterilized and you don't want dirty jewelry in a new piercing. Wait at least a month before wearing acrylics. However, you can wear bioplast. Which is a flexible plastic bar/ring. It can be autoclaved so it's fine.
Most of the time its just clear plastic jewelery.
No. Retainers are made of plastic which is not suitable for initial piercing. Initial piercing should always be done with a titanium barbell.
you can buy them at any walmart
No you are pretty much stuck with it unless you want to see a plastic surgeon $$$$.
Bioplast or PTFE the size is not one size fits all you need to tailor the piece to the piercing. See your piercer for detailed help.
Typically a new tongue piercing will discharge for 6 to 8 weeks and then ease off as the fistula* is formed (*fistula is the tube of new tissue that makes up the actual piercing hole). Swelling is at it's height for about 2 weeks (14 days post piercing) then once the swelling has eased it's a very good idea to have the piercing jewellery downsized to avoid dental damage from biting the jewellery. Plastic barbells are not recommended for new piercings and actually can fail due to the swelling leading to swallowing or inhaling the plastic barbell. A tongue piercing like any piercing is never to be considered fully healed until it's a full year old, you can have a light heal but it takes a full year for the piercing to season up allowing for removal or the jewellery for extended period of time.
