buy a longer axle and put bearings on one side of the axle
I'm assuming you're talking about an BMX here... Undo axle nuts, put pegs on. With an extender and a socket wrench, get the axle nuts back on and crank down.
axle mounted, yes.
The teacher told us to hang our coats on the pegs.
Different BMXes have different axle sizes. Easiest is to measure what you've got.

Oversized rainbow pegs are Bigger, easier to use and require a longer bolt.
Usually not. A peg has to thread onto an axle and mountain bikes generally use quick release skewers so the axle is very short. But if you have a MTB with solid axles (some MTB dirtbikes and low-end MTBs have), or go to the effort of having the q/r axles replaced with solid axles, then it's doable.
Yes, so long as the pegs are secured into the hand-tool.
Use a socket wrench to unscrew the pegs then once they are off, put all the parts back the way you found them.
It depends on what is your peg like. 4 small pegs or 2 large pegs a day are considered normal and they are not dangerous. The question is how long you can hang on to these 4 small pegs. Ask God to give you all the power not to increase the number of pegs from 4 small pegs to 4 large pegs; from 4 large pegs to 8 large pegs, from 8 large pegs to 16 large pegs and so on.
BMX pegs can be bought online from Chain Reaction Cycles. The pegs are in a range of sizes and colours such as blank value pegs and P3 pegs. BMX pegs are for those who want to do extreme cycling or stunts on a bike.
