#3 are Thermos water bottles. I like the stainless steel ones with plastic straws. I first bought a character one after my son broke two water bottles (nice brand) two weeks in a row. I didn't think the Thermos one would last his rough behavior but it did! So then I started buying ones for my other kids and myself. It's amazing how ice will stay for hours in these. :)
I found out on Amazon, that you can order replacement straws directly from Thermos! You can also order replacement lids if you need it. You need your model #. Thermos 1-800-831-9242. $2 for replacement lids, $1 for straws (you can order 5 per week per model). S&H is maybe $3.50?
Here's the kids, there's all kinds of characters available
Here's the 16 oz Purple one I like, also available in gray
model #HS4010 for 18 oz pop of pink (for my reference!).
I would suggest only serving water in these as the straws seem to get gunky and moldy pretty fast if a different beverage is served. :)
