I'm 5'1" female and have fireman lifted grown men and carried them some distance like that. The amount of weight is potentially liftable by a single woman, never mind two. Granted I'm not average strength for my size (history of doing judo, ice hockey, rugby and power lifting) but neither am I superwoman (my powerlifting best lifts are intermediate to advanced, but have never been elite, and that's relative to my body size and gender). BUT It's also a lot easier to lift someone who's alive and conscious as they will tense up and get in positions that make it easier for you to lift them.
It's said that the term "deadlift" (lifting the barbell off the floor until you're standing straight, shoulders back) comes from lifting up dead people. (although I've never fact checked that - it could just come from lifting a dead weight) Two women ought to be able to deadlift, together, the weight of an average man quite easily. The difficulty would be that because he's dead it would make the whole thing very awkward. Lifting a dead body is way more awkward than lifting the same amount of weight on a barbell. Note: I've never lifted a dead human, funnily enough. However if you had a brave volunteer who is able to be 100% relaxed while you try to lift him you could simulate it, to get an idea of just how awkward it would be.
To get over the non-rigidity of the body (I assume there's no rigor mortis yet) I would suggest making a sort of stretcher (e.g. a plank of wood or something flat and rigid that they could roll him onto, then they take each end and deadlift him off the floor (bent knees, back straight, let your legs do the work). When they get to the balcony, they'd have to raise the stretcher up which would require a bit of technique. You'd have to get down low (don't lower him too much while you do this) so the end of the plank is resting on your chest with your arms supporting it for balance, but not taking too much weight, then use your legs to raise the entire plank upwards - the two of them would have to co-ordinate this. For men and women, but especially for women, the legs are a lot stronger than the upper body so any lifting like this, the more you can get your legs to do the work, the better. Being able to do arse to grass squats would help a lot with this (this is a good example of the functional ability you get from being able to do arse to grass squats). If there's furniture on the balcony, e.g. a picnic table, then lay the stretcher on that and then you can have a little rest and then you only have to raise the plank a bit higher to tip the body over the balcony (you still need to raise the plank the same way, i.e. plank resting on chest, knees bent, back straight, lift with your legs). Once the plank is level with the balcony, it shouldn't be too hard to tip him over. They'd have to co-ordinate this.
Anyone who's done lifting and handling training for a manual labour job ought to be able to do this, not just people who've done powerlifting. However if that doesn't fit your characters' backgrounds, you might want an alternative method.
ETA: anyone who's worked in nursing and caring type professions would've done training for lifting patients - their techinques would be different to the above - that's an alternative way to do this. Also there's a two man carry technique that paramedics, mountain rescue etc would know. NOt sure how easy any of these are to do on someone who's actually dead and can't co-operate in any way, but presumably they've been done on unconscious and dying people before. The techniques would probably be better than my suggestion. the overall point remains the same - with good lifting techniques two women of ordinary strength levels shouldn't find it too difficult.
but my wife did once fall when we were out and although she climbed stairs when we returned, she just couldn't make it beyond the top landing and lay on her back.
