This is a very closely guarded secret, known only by Santa Claus. If everyone knew it, then anyone finding their way to Santa's secret workshop would be able to command the reindeer to fly.

Of course you can see a picture of Santa flying!
If you have 666 reindeer and want 444 to fly your sleigh, you will have 222 reindeer remaining on the ground. Since they fly in a single-file line, you can line up the 444 reindeer in that formation as they take off. This setup allows you to efficiently utilize the majority of your reindeer for the sleigh while keeping some in reserve.
Reindeer are definitely real, they can be found to this day in northern European countries. As for flying reindeer, there I have no answer because I haven't seen reindeer fly .. myself.
No, only Santa's do.
