Answer:

In Neutral lipids there are triglycerides

diglycerides

monoglycerides

free fatty acids

cholesterol

cholesterol esters...

hexane/diethyl eter/ acetic acid (70:30:1 and others) is a good elutant mixture to separate them. Other combinations are needed for phospholipids separation...look for "thin layer chromatography silica gel" articles, there are plenty of reviews and plenty of elutant mixtures and the conditions for silica columns are quite similar.
