The average Brix of apple is 13.3, or SG=1.0538, but you'll need to measure what you are using to see what yours is.
Using Fermcalc with the following parameters, Honey @ SG 1.4142, Target SG of 1.080, Initial SG of 1.0538, Initial Volume of 5 gallons, you would need 4.379 pounds of honey to get your SG to 1.080, and you'd have 5.37 gallons of liquid.
If my sugar parameters for the juice and honey are correct, and you use all of the honey, your beginning must would have SG=1.134 and be 6.33 gallons. Beginning SG of 1.134 would yield a wine with ABV approaching 20%. Since no yeast will ferment to 20% (EC-1118 will do +/- 18%), you'll end up with rocket fuel and residual sugar.
Having said that, were I you, this is what I'd do, start with 6 gallons of juice to make sure you end up with a solid 6 gallons, and add your honey slowly, mixing well to ensure proper readings, and use your hydrometer to get to your target of 1.080. As a guideline, using the same parameters as above, 6 gallons of juice would need 5.25 pounds of honey to get to the target 1.080. Again, your juice and honey may have different SG's than the ones I assumed. Hope this helps.
