I have a Vegan question?!
Answers:
Nesquik cereal is loaded with sugar. This sugar MAY not be vegan, though the company may introduce raw sugar which is not whitened through a process known as bone charring (a lot of cereals do not use this charring process, but I have no idea about Nesquik). Also, honey is considered a bi-product, though I highly doubt Nesquik puts honey into their cereals.
As for Bisquik, yes it is vegan.
Just replace it with soy, rice, ect milk (it may not be as thick as usual, though there are thicker soy milks which have a questionable product known as carageenan). Some people add flax to it as well.
2 cups Bisquik : 1 cup soy milk
Nesquick Cereal is Vegetarian
Bisquik is Vegan... sub soy or almond milk & Tofu, bananas or a commercial egg substitute.
Bisquik isn't vegan, not sure about the rest of your question, sorry.
Being vegan seems pretty unhealthy, no offense. Vegetarians can struggle to get a balanced diet so you should really have some strong reason for being vegan.
