Assuming you are not on an international flight where you'd have to declare the fruit, if the fruit cup is packed in liquid or syrup, you may not be able to bring it through security in a carryon. If you put them in checked luggage, bag them to keep them from leaking.
The large bottles of aerosol liquid items can go only in checked luggage.
She IS on an international flight. Therefore the agricultural regulations do apply in this case, whether in carry on or checked luggage.
OP, if you really do want to bring milk, juice, pop, water, Lysol, fruit, etc honestly our recommendation of Garden Grocer or a trip to the store really makes the most sense. A gallon of water at Garden Grocer is listed for $1,49; a 24 pack of 17 ounces $7,99. A can of Lysol is $6,89. You are stressing about making your domestic to transborder connection, yet you are making it more difficult for yourself by trying to pack these items.
To me the stress is worth the few dollars more it may cost you.
Will you make it through with your prohibited items? Possibly. People do every day. But every day people are also stopped, denied entry, delayed and miss their flight, and/or have an entry into their profile. I cross borders somewhere in the world almost every week, and I see it happen virtually every single time. It may not have happened to people here, but it does happen every day.
I was once on a bus from Canada to the US. Another passenger had a Subway sandwich in her purse, and she was told to toss it. She was in tears and the guard relented and told her that she could take it IF she removed all prohibited items - the meat, the tomatoes, the lettuce, the onions. She was left with bread covered in sandwich spread. Of the 18 or so passengers on the bus, only 3 made it through the border.
I've seen families turned away due to a stray orange or apple. Many people here will tell you that it's 'fine' to take those items, but if you are stopped, and miss your flight, or turned away, or you or your children have an agricultural record, it will impact you.
Honestly, for the few dollars really do consider saving yourself the stress and worry over these items. It will make your vacation more enjoyable if you start it off right.
As a disclaimer I myself have never used Garden Grocer, but they do get good reviews here.
