Yes. There are two methods ...
(1) In Hyperlobby, click the first slot on a vacant coop list (for a coop mission) or in the open mission list (for a dogfight mission). You can then set the mission difficulty settings. Get your mate to also click below your name in the same list. Then you hit the blue button at the top of the list then hit fly. HL will automatically minimise & IL2 will automatically start & you (the mission host) can then select the mission you want to play. Your mate's game will automatically load with the mission you selected.
(2) Load a game yourself, get your mate to go to multiplayer-connect & type in your direct IP address to connect to your game.

I've set a mission up in FMB but not sure how to copy it over to Co-op missions folder, or if it's even possible to play through hyperlobby...I assume I'll need to send a copy of the FMB file over to my mate for him to save???

No. You don't have to send him a copy of the mission. When he connects to your game (as above) the mission is automatically downloaded to his computer.

P.S. weirdly I can see mission files in the online folder, but I can't see the files for any missions I've created in FMB. Is that normal...I remember in OFP and ARMA that I could save them as user missions in single/multiplayer but can't see any way of doing this in '46

FMB missions can be saved into a folder in the coop section or into a folder in the net-dogfight sections of your missions folder structure. Have a look at the missions-folder structures in windows explorer. You can copy missions from folder to folder using the standard windows copy-paste method, just remember that every mission has two file; one called MyMission.mis & another called MyMission.properties.
