Yes. Polar and Non-polar are gradual. For instance, for a bond, an electronegativity difference >1.7 is called ionic, and less than 1.7 is called non-ionic. But the difference is 51% bond polarity versus 50% bond polarity!!
There are London Dispersion Forces (a subset of van der Waals forces) which will always cause molecules to be attracted to each other. The lower the temperature the stronger the attraction. This even applies to helium, which can be condensed into a liquid at 4.2K.

No, polar and nonpolar molecules generally do not mix well together because of their different intermolecular forces. Polar molecules are attracted to other polar molecules due to their uneven distribution of charge, while nonpolar molecules are attracted to other nonpolar molecules. This difference in intermolecular forces leads to poor mixing between the two types of molecules.
In chemistry, the saying goes, "like dissolves like" with respect to polarities. Water, which is polar will mix/dissolve any polar substance. Salt (NaCl) is polar, and therefore it dissolves. All lipids (wax, oil, fat) are non-polar and do not mix with water.
Polar substances are only attracted to polar substances. When talking about solvents and solutes, only polar solutes can dissolve in polar solvents. It is the same for Nonpolar solvents as well. So, I hope this helps! :-)
Hardly.
Almost no sugar or salt in petrol and lots of them in water and bit less in ethanol.
Two polar substances will mix as will two non-polar substances. However, a polar and a non-polar substance will not mix.
You it is possible.However it is more favorable if you can mix a polar solution in a polar solution and a non-polar solution in another non-polar solution.
Polar molecules, such as salts and sugars, would mix best with water due to their ability to interact with water molecules through hydrogen bonding. Nonpolar molecules, like oils and fats, would not mix well with water because they lack the necessary polarity to form interactions with water molecules. Symmetrical molecules would not have a significant impact on their ability to mix with water, as symmetry does not affect polarity.
Polar substances dissolve in water because they have similar polar characteristics that allow them to interact and mix well. Non-polar substances, on the other hand, do not dissolve in water because water is a polar molecule and cannot effectively interact with non-polar molecules.
Cyclohexanone and benzophenone are both non-polar molecules, which allows them to mix well together. Water, on the other hand, is a polar molecule that does not mix well with non-polar substances. This leads to poor solubility of cyclohexanone in water.
If polar and nonpolar solutions are mixed together, they will not mix and will form separate layers due to their different polarities. This is because polar molecules are attracted to other polar molecules, while nonpolar molecules are attracted to other nonpolar molecules.
Baby oil is nonpolar because it is composed of nonpolar molecules like mineral oil and fragrance oils, which do not have a net charge distribution. This means that baby oil will not mix well with polar substances like water.
