Q #1

no knowledge would not be more valid if there is simply more people that believe the same thing. It just increases the number of people that agree in this world....it does NOT mean that it is valid or the right thing. For example lets say you have 90% of the people in the world that believe that killing each other is the 'right' way to do things.....well does the larger number mean that it is the 'right' thing to do? i dont think that in this life there is any actual way of proving validity of a belief or anything else for that matter.

Q#2

I think this one is a free for all. You only have to prove your beliefs if they get you into trouble XD

1.Knowledge is valid if it's based on truth and fact. Simply because the majority of people accept knowledge as true does not make it so. For centuries people believed the earth was flat. But not one of them ever fell of the edge.
2. For some things it is good to have evidence to support our beliefs. Examples would be the consequences of uncontrolled sexual conduct and or drug use. For others things, such as certain aspects of religion, we take some things by faith. It is important to know why you believe something. For your own personal benifit, it gives you something solid to build your life on. For others, knowing why you believe, helps you explain it better. It increases understanding of each other.
Hope that helps.

Yes this IS my response. (downward)

Q.1
Validity is determed by how much the statement actually supports an argument or belief. For example, imagine I was trying to persuade people that the sky is green. I persuade 1040 people that the sky is green but the fact that those 1040 people believe me doesn't change the fact that the sky is clearly not green
Q.2
The extent to which we need evidence to support our beliefs really depends on what belief you are talking about and the type of person the beliiver is. For example, somebody who is religious have their religious text (The Bible, the Qur'an, etc) and their own faith as all the evidence they need. Other people need evidence for anything and everything under the sun. Most people are somewhere in between.
Hope that's been helpful.
