• Backpack: Is it any good? Will it fit whoever is to wear it? Will it hold up?
• Food and water ( unspecified amounts): I strongly prefer hydration bladders for carrying enough water to matter -- this kit sounds like it doesn't have enough water to matter.
• Emergency blankets: Cheap mylar blankets are better than nothing but I would throw them out and replace with Heatsheets.
• First aid kit: Addressed above.
• Two 12-hour safety light sticks: Waste of space, would throw them out and replace with a quality LED flashlight and extra batteries.
• Dust masks: Good.
• Nitrile gloves: Good.
• Emergency whistle: If it's a good one, good.
• Emergency ponchos and pocket tissues: Emergency ponchos are much better than nothing but I would prefer a real rain shell and a fleece for each person in your party. Pocket tissues are a nice-to-have but I don't include them in emergency kits, as I can always come up with something I'd rather include.
• 10 cotton tip applicators: Huh?

I don't see any fixed-blade knife, multitool, flashlight (mentioned above), headlamp, fire-making, cordage, navigation, sun protection, bug protection, or water disinfection. This doesn't look like a kit I would buy.
