Because I have plenty to talk about concerning weapons, I'll start with what course of action we should take first.
b) Keep walking. The most important thing right now is to get out of the city. It would be a good idea to ask the survivors where the zombies are congregating most; that way you can head in the other direction. But you shouldn't hole yourself up with a group that big. There's always the odd chance that one or more of them are infected.
As for weapons, I would have suggested taking a pump-action shotgun, but that kind of weapon wasn't among the options listed. That means I'll have to go with...
5. An AR with a 16" barrel is compact enough to use in tight spaces and has the range to hit a target at about 200 yards (depending on the weather and how good your aim is). Most dealers you come across will carry AR parts and .223 Remington is one of the most common types of ammunition available in the U.S. Finding ammunition and replacement parts for your gun shouldn't be much of an issue.
The M1 carbine would be my second preferred option. It's tough, compact and easy to use, but .30 cal just isn't as easy to come by as .223.
A handgun is perfect for when you get grabbed by a zombie and need a quick way to kill him, but aiming a handgun requires you to hold your hands out to get a better shot. It'll be easier for a zombie to grab you in that instance, so it's not worth using one unless you need a backup weapon.

Convenient, but having two snipers in a group can be redundant. Besides, you probably wouldn't want to shoot a zombie unless it were up close anyway.
Bolt-action rifles in my experience can be very glitchy. Post-war models like the SKS are very reliable and very accurate weapons. However, someone who is inexperienced with firearms is going to have a tough time using a bolt-action. Even if properly oiled and maintained, the bolt-action can be very stiff, and it can be easy to jam your weapon by cycling too fast. Most of these rifles are also quite heavy compared to the other weapons available, are cumbersome to use in close-quarters, and have a pretty low rate of fire since you have to cycle every shot by hand. Bolt-action rifles are good for sharpshooting, just not for room-clearing.
A shotgun would be nice to have, but not a double-barrel. Besides being a hassle to reload, most modern double-barrels fire both shells at once, meaning you'd be wasting two shells in one shot. Again, I would choose a pump-action shotgun over everything else available, but I wouldn't take this.
All issues with handguns apply to the .44 Magnum revolver, except now you're limiting yourself to only six shots. .44 Mag is serious overkill, and firing it will break your wrist if you don't have a good grip on the weapon. If you were going to take a handgun, you would be better off grabbing something with a lot less kick.
