I can only answer the second part of your question. As far as attraction goes, polar is not the opposite of nonpolar. Polar in itself has two opposites: positive and negative. Those two are the opposites that attract; a positive region of a polar molecule is attracted to the negative region of another polar molecule.
Molecules will always attract each other unless they are negative. In which case tthey will push each other away.

Typically nonpolar substances are soluble in other nonpolar substances. Like disolves like...

Water and oxygen molecules do not attract each other because both water and oxygen molecules are nonpolar. Nonpolar molecules do not have regions of positive or negative charge, so they do not exhibit attractive interactions such as hydrogen bonding.

Nonpolar bonds occur when the electronegativity difference between atoms is less than 0.5. Electronegativity measures an atom's ability to attract electrons in a chemical bond. In nonpolar covalent bonds, atoms have similar electronegativities, resulting in equal sharing of electrons.
The bond between oxygen and hydrogen is considered polar because of the difference in electronegativity between the two atoms. Oxygen, being more electronegative, will attract the shared electrons more strongly, creating a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atom.
No, water molecules are polar and are attracted to other polar molecules, while nonpolar molecules like oil are not attracted to water. This is why oil and water do not mix - the polar nature of water causes it to exclude nonpolar molecules.
The nonpolar solute is dissolved in the nonpolar solvent.

Detergents have molecules with both polar and nonpolar parts, allowing them to form bridges between polar and nonpolar molecules. The polar part of the detergent can interact with water (polar) molecules, while the nonpolar part can interact with nonpolar substances. This helps to surround and solubilize both types of molecules, keeping them mixed together.

Oxygen forms a polar covalent bond, not a nonpolar covalent bond. This is because oxygen has a higher electronegativity compared to most other elements, causing it to attract electrons more strongly and create a partial negative charge on the oxygen atom.
