In order to get the oil filter housing off you will have to use a specific tool.
This is the part# 09228-06501. It can be purchased from online or your local parts store might have it as well.
You might be able to take it off with a large enough channel lock, but you might damage the housing.
Here is a very good video of the process for the RAV4:
The total capacity is 6.4 quarts of oil.
I have attached the complete procedure for your reference.
Please let me know if you have any questions.
