If your pocketbook can handle the cost, you could blend as many oils together as you want. As Judy said, the shelf life of the blend will be equal to the shortest shelf-life oil.
That said, have you actually tried these oils to see what they do for your skin? Fewer carefully-chosen oils might be just as or more effective. It is very tempting to buy every oil that sounds like i t has amazing properties, but mixing them all together doesn't necessarily result in a superior product.
As far as skin feel -- what is too greasy for one person is just right for the next, so you will need to experiment to find what is right for you.
If you are making a product that is 100% fats, it will be greasy -- there is no way to get around that. You could add a modifier like cetyl alcohol or a starch (corn starch, tapioca starch, etc) to reduce the greasy feel slightly, but there are limits to what these ingredients can do.
If you want the product to be less greasy, you will need to look at making a cream or lotion with an emulsifier, preservative, and water. Then you have more options to change the skin feel.
I recommend checking out Susan Barclay Nichol's website
http://swiftcraftymonkey.blogspot.ca/ for a lot of very good articles on lotions, creams, salves and the ingredients that go into skin and hair care products. Susan is the "go to" girl on this topic.
Edit -- A whipped body butter made with 100% fats must have a large percentage of solid fats. Only the shea and cocoa butters qualify -- all the rest of the fats you list are liquid oils, including the coconut. They won't make a stable whipped butter. Again, check out Susan's blog for more info and recipes.
