I think the five (specific) items would change a fair amount with climate and season. We're in a drought, and the ability to carry water in a bottle outweighs the other uses a pot has for me.
Due to the drought, all camp fires are banned. The risk of starting a wildfire is too great, so this will influence my kit. There are many wild edibles in season at the moment, so food isn't a real concern, nor is cooking.
My main concerns would be staying hydrated and warm at night without fire.
For my area in mid summer, I'd take...
Wool blanket.
SS Water bottle or canteen.
Water filter.
Tarp.
Axe.
As an aside, I am not counting a sixth item as I consider it a necessity in my woods. Bear spray. I live on Vancouver island which has the highest population of mountain lion in North America, and the black bears are no less abundant. It's always a good idea to keep some spray on hand.
