I only need 1 size from the kit. Is there any way to buy just one size?

Not unless you go to the store. I found the other ones come in handy sooner or later.

Are these o rings suitable for espresso machines?

Maybe the“KEZE 660 PCS Clear Food Grade Silicone O Ring Assortment Kit”is more suitable for you

can they tolerate gasoline?

An O-Ring by its very nature is a gasket that seals a connection of some kind. It should not come in contact with any kind liquid be it water, milk, or gasoline. If there is a failure of an O-Ring, it is the wrong size or the connection is of poor quality.

Do the smaller (1 in) gaskets work for a waterbottle spout?

I don't know if it would fit or not, but these gaskets are clearly not food grade.
