Is there an infinite (edit: but finitely generated) group G such that for all g in G, |g| is finite?
If so, how many such groups exist?

Yes, as per Ryan's comment you can just take an infinite direct sum of finite groups. However the more interesting problem is: are there (infinite) $\textit{finitely generated}$ groups with all elements of finite order?
The answer to this was open for a long time, but it is indeed yes. In fact this was known as Burnside's problem
The first examples were given by Golod & Shafarevich.
There is a lot of info on the wikipedia page
