According to Greek and Hebrew, I think they fall into 4 basic categories. However, with the recent types of "modern love", I am sure there are probably closer to a dozen.

I'm sure there's some artificial categorization that can be ascertained, but I believe there are as many types of love as there are people;)

I'm sure there are many different types of love. The best of them all in my opinion is unconditional love.

Parental, romantic, platonic. :)

love to living thing love to non living things(like emotions feelings etv )

"In Aramaic, the language that Jesus spoke, there are six words for Unconditional Love (Kenoota, Khooba, Makikh, Abilii, Rukha and Dadcean Libhoun) which are untranslatable and are all translated as the one word “Love” in the English Bible. " http://en.wikipedia.org/wiki/Love "Kenoota: - describes a mind-set of "hunger and thirst for Fairness-for-All," of wanting Fairness for All more than food or drink, i.e. being willing to make some sacrifices for it.[...] One who practises Kenoota will become increasingly aware of the interrelationship of everything and everyone Khooba: - is the mind-set that is first of all an intention to have complete openness to seeing, and giving attention, to the good - in oneself, others, and in Life. Without it the mind tends to scan only for "badness" in various, sometimes devious, ways. Makikh: - A mind-set, (goal/attitude combination), which is openness to perceive truly and accurately the needs of others from their position It includes the deep desire (goal) to meet those needs if practical, that is, to give Service. It is the basis for looking for "win-win" solutions in relationships, business, and international affairs. Abilii: - the relief of mental stress A mind-set that is openness to compassionate Self-correction. A mind-set , set in place by an act of Will, which has the goals: (i) of allowing errors in one's own mind-processing to come into awareness, joyfully, and with love towards oneself for so doing, and (ii) of revisioning correction of the error(s) with love and joy rather than self-castigation, self-denigration or remorse. The intention is to learn from the errors and enjoy the self-development that follows. Rukha the Home, or Source, of Peace: - This word conveys more than just "peace of mind". To be "at Home in Rukha" means to be in contact with the place of deep inner serenity that exists deep within each person's Self, to feel and to be in harmony with one's self and others, whatever the outer circumstances are doing. Dadcean b'Libhoun - the vision of wholeness: - Connected with your Higher Self, you are enabled to "see" with greater purity, to see things whole, from a greater perspective, with no faults in the mind. As if from a mountain top, from this more elevated and broader perspective you can also look down on your personal life on earth, and see the inter-relatedness of past, present, future, and the interdependence of different people and peoples, the human family, and the other creatures who share this planet."

I believe there is only one type of love with many different degrees.

There can be as many types of love, but the number one love is UNCONDITIONAL LOVE.
