First, you have too much double quotes on your columns name. I openned your CSV with openoffice and all the columns name had quotes around them. For example, if you open your CSV with notepad you will see that it starts with :
"""product_id""","""product_parent_id"""
However, it should be:
"product_id","product_parent_id"
I don't understand why you have an integer in the product_parent_id column ? This column is to be filled only for variants. Since your products are not variants, that column should be empty on your CSV. That's why the system considered your products as variants. If you empty that column and import your CSV again, you will see the category/related/options, etc areas.
That's also why your products were not displayed as they were in fact variants and not products for the system.
