I would not keep the spaghetti & pizza sauce once opened for more than 7 days. Salsa could be kept for alot longer due to its pH and water activity.

upto 10 days max would be a safe bet

Once opened, i would not suggest you keep them for more than 5 days.

With spagg sauce etc, you can however, put the leftovers into a plastic dish/bag & freeze them

You can keep them there as long as you want, but I would avoid eating anything that has been there more than 2 weeks, assuming they are well sealed.
