Thats a lot of different oils. U use all them in your diet?
No - you do not need to use of of them.
There are only 2 essential fatty acids. One is an omega-3, and one is an omega-6.
The omega-3 oil gets converted to EPA and DHA in your body - which are responsible for lots of beneficial actions in the body.... but it does so very inefficiently, so it is much better to get the EPA and DHA in your diet.
You also need the primary omega-3, which you can get from plant sources of omega-3 such as flaxseeds and walnuts (it is also in small amounts in vegetables and some legumes).
For your omega-6, you usually get sufficient amounts in your diet from nuts and seeds (as well as grains, legumes, vegetables, etc) so you usually do not have to worry about supplementing this at all... If you DO supplement you run the risk of OVER consuming your omega-6 fats - and this throws your omega-3 to omega-6 ratio's out (which are important for health too).
Then there are other healthy fats - which are your other poly-unsaturated fats (eg: nuts, seeds) and your mono-unsaturated fats (eg: olive oil, avocado). These are very healthy fats and can/should be in your diet as well, BUT they are not ESSENTIAL as such (that is, your body can do without them).
Basically, supplement your fish oils (6g a day is fine in my opinion, but, as jodi suggested, you can have up to 10 if you wish) then ensure your diet has a good mix of nuts, seeds, grains, legumes, vegetables, animal products (eggs) and throw in some olive oil or avocado as well and you will be set!
