EasyJet Twighlight Check-in Dilemma - Help Needed

My boyf and I are flying up to GLA on Sat 17th and for the first time need we take hold baggage on this illustrious airline. We have just paid for the privilege of taking 2 bags between the two of us and it says that it is 2 bags is on the PNR between us (not 1 per person) so I assume can check them both in myself.
My other half has a leaving party at work on the Friday night so will be in no state for the early start for a 07:15 departure.
I was thinking about going to LGW to dump the bags on the Friday night after 8pm so we can start a little later. Of course T can't go so I will have to go alone.
Does anyone know if:
1: I can check in the two bags for me alone?
2: I can check T in at the airport without him being there?
3: If I have checked myself in at the airport but not him, can T then check-in online?
I hope you can make sense of that and your input would be greatly appreciated.
