For the ballpoint pen stains I recommend acetone.
Pen ink is a mixture, so the word polar cannot apply to it. Its individual components may or may not be polar, depending on what they are (there are lots of different inks). If it's water based, then water is polar.
Glucose is soluble in ethanol.
Yes, ispropyl alcohol is water soluble in all proportions.
they want somewhere to go and they want to move so they are separated by ultraviolet distinctions.
According to the US Pharmacopeia, codeine in free base form is freely soluble in ethanol. However, codeine phosphate, common in many formulations including codeine, is only sparingly soluble in ethanol.
Most inks are solutions.

Most felt pens use alcohol based inks, so unless your dining table is finished with shellac (which uses alcohol as a solvent) which is unlikely, a little alcohol should take of the felt pen marks. Test in an inconspicuous spot first to see if it effects the finish.
Some fountain pen inks known for their good ink flow include Pilot Iroshizuku, Waterman, and Sailor inks. These inks are generally well-regarded for their smooth writing characteristics and consistent flow. It's important to note that ink flow can also depend on the nib and pen being used.
methyl alcohol is not soluble in hexane
DNA is not soluble in alcohol.
Most types of ink can be removed by blotting the clothing with a paper towel soaked with isopropyl alcohol. Some "permanent" inks really are permanent, and cannot be removed.
Clindamycin HCl is very water soluble, while only slightly soluble in alcohol.
Fountain pen ink is made up of a blend of solvents, pigments, dyes and water. The mixture of which can create characteristics that make your writing experience different. Some inks are washable, others are permanent. PH Levels range from around 2 to at most about 8 so there is a wide mix of high acid inks and high akaline fountain pen inks.

Ball point pen ink is generally not water soluble. Once it dries, it forms a semi-permanent bond with the paper or surface it is on, making it resistant to water. If the ink is water soluble, it would smudge or run when exposed to water.
Iron is not soluble in alcohol. Iron is a metallic element that does not dissolve in alcohol, which is a polar solvent. If you need to dissolve iron in a solution, you would typically use an acid or other specialized solvents.
