There isn't exactly something known as a non-polar lipid.
A lipid consists of a polar phosphate 'head' and a non-polar hydrocarbon 'tail'.
When something is 'polar', it means that that the charges between a compound aren't shared equally. For example, in water (H2O), H has a slightly positive charge while O has a slightly negative charge.
Since the 'head' of the lipid is polar, it attracts H2O molecules and so it is hydrophilic. On the other hand, the 'tail' of the lipid is non-polar, hence it is hydrophobic.
Lipid
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
Nonpolar lipid layers
Water is polar, but lipids are nonpolar.
Yes because the lipid bilayer is polar.
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.

Gravity?? Real answer: Because the skin contains nonpolar lipid (fats) molecules.
Lipids are miscible in nonpolar solvents because they have a nonpolar nature due to their hydrophobic tails. The nonpolar solvents can dissolve and interact with the nonpolar lipid molecules. On the other hand, lipids are not miscible in polar solvents as there is a mismatch in polarity, making it difficult for the polar solvent to dissolve the nonpolar lipid molecules.
Nonpolar lipid layers
Nonpolar CH bonds. Ester linkages occur.
Yes because the lipid bilayer is polar.
