I can make multiplayer games?
You can use Corona to create all sorts of multiplayer games, yes.
Now, can you, i.e. specifically you, create multiplayer games on Corona, is completely dependent on your skills.
is the multiplayer you are referring to via Bluetooth, the internet or wireless LAN
Are you building a two-four player turn based game? Are you wanting to build a game with many players running around in the same world? Are you needing very low latency? There are many many variables that you need to consider.
Corona can work with all of these, but the tools you need and the difficulty changes with each possibility.

Would not recommend bluetooth because it does not work cross platform between devices android and iOS. Plus very few games still use it.
For wifi multiplayer I recommend https://github.com/roaminggamer/AutoLan-IPv6
