Hi Regyn,
Welcome to the forum.
I am Simon.
I'll try to answer your questions as much as possible.
1. Does this seem normal?
Yes it does seem normal. Did you just got your corn snake not too long ago? Maybe he is just used to the environment and feels comfortable in there. Nothing much to worry as long as you are sure that the temperature is around 80-85 during day time and around 70-75 during night times.
2. Should we continue to feed him once a week, which will disturb the hibernation?
This I would really need to know how long your snake is. But since you said that your snake is around 10 months old, I would not recommand burmantation or hibernation. (Burmantation is what we call it for snakes and others that are not really going to sleep....just slow moving and everything slows down) The reason why I wouldn't recommand burmantation for your snake is because it might be a bit small to go through it. Maybe in the wild some of them can go through a long cold winter but a lot of them can't. So instead of letting them go to burmantation, keep the temperature at the normal temperature. Keep feeding. Under burmantation, you don't feed, dont have heat just water.
3. If we leave him alone and let him hibernate, how long should that be and should we expect him to be a little edgy? I wouldn't want to not handle him for months and then have him be difficult to hold and handle.
For a normal burmantation, it's no feeding at least a week before the actutual brumantation. Then slowly temperature in the tank/enclosure drops to around 40-60. This process really depends on how each person views it. Some let them burmantate for 1 month some 4 months...I usally do it for 3 months.
Hope this helped you.
