After going through the literature only virgin olive oil looks like help to increase HDL. However, olive contained high amount of omega-9 than omega-3 which may induce inflammation. Despite much hype, there is no good literature to suggest that coconut oil is good for increasing HDL. It increases cholesterol level significantly due to high saturated fatty acids. Flaxseed oil too fail to increase HDL.
Prashant,
The recommendation for diet is to consume fish high in omega-3 fatty acids. Fish have DHA; whereas flax oil has ALA which needs to be converted and some people have difficulty converting it. Below is an article based on evidence from the Pakistan Medical Association.

According to Crawford and Paden (the Journal of Family Practice), exercise and tobacco cessation, along with DASH diet and a low-carbohydrate diet with iso-soy protein have resulted in significant reduction of HDL-C. Attached, please find the article.
According to me and as far as I have known through the available scientific communications, no oil would be able to synthesize any extra amount of HDL except providing the normal continued synthesis of HDL in a particular person.
Dr. Richard Kones write up gives a good account of the present day knowhow but things are not proven conclusively.
As far the question is concerned i do not think
any oil can raise HDL substantially over and above normal synthesis in an individual.
Functionality of the HDL should be the focus but not the quantity. HDL must be synthesized by the body from precursors mostly present in food. In my view, no single oil or food source can give the expected higher HDL level that this question seeks to explore. Several factors are necessary to ensure high level and functional HDL even if the'ideal' food source is found.
The views of Dr Samuel Acquah are quite logical
and supportive to my answer given earlier.
A Cochrane review, that including almost 60,000 people who have been in studies assessing effects of reducing saturated fat for at least two years each. Together the studies provide moderate-quality evidence that reducing saturated fat and replacing it with polyunsaturated fats reduces our risk of cardiovascular disease. (Ref: Hooper, Lee, et al. "Reduction in saturated fat intake for cardiovascular disease." Cochrane database of systematic reviews 6 (2015).
Thanks Abu for sharing a valuable reference. I come across flaxseed, olive oil, etc. but these oils also contained omega-6 with can generate inflammation.
I am of the opinion that no single oil or fatty acids would raise HDL. Apparently all lipoproteins types viz. HDL LDL and VLDL are all synthesized from fats and hence its composite phenomenon and.for raising HDL one should adopt other means such as walking, exercise and possibly may be moderate amount of alcohol consumption.
