Yes.
¿Por qué son tantos los memes en español?
There can be infinite memes, as people make them up almost every day, so they are uncountable. Sorry.
Over 40 ;)
A lot, and for the sake of human existence and my sanity, a lot more after that. I hope the memes never end.
Harmless memes
So many it's impossible to count.
Do I really need to explain?

Memes have been around as long as humans have been, so nobody invented memes in general. A meme can be just about anything that is passed around though a society. Specific modern day internet memes have creators, and there are so many famous memes that it would be best to check out the meme encyclopedia "Know Your Meme" for info on any meme you need.
