Spells are energy and focus, if you have enough energy to put into the spell, and are able to focus your attention on the task at hand, you can cast as many spells as you please regardless of materials or purpose. With that said I wouldn't say it's wise to cast more than one or two in a day otherwise you'll run into energy problems.
Also, some believe casting too many spells at once can cause a clog in the system. Some feel the universe/Gods might get tired of you calling on cosmic powers to find your car keys or help when you're having a bad hair day and decide to teach you a lesson. You might also run the risk of one spell backfiring for whatever reason and if you cast say 14 spells in a week, you won't be able to figure out which one was responsible.
It is best to cast one spell and give it time to work it's magick. Cleansing and protecting your home then making a honey jar for love and a money satchel in the same day is fine in theory, but think how tired you are after a big day of house cleaning, spell casting can have the same effect. If you feel you can, go for it though.
