Do these sentences make sense and can I use "keep from" here?
1 She wants to keep everyone from knowing the truth.
2 she wants to make everyone not (to) know the truth.

Sentence 1 is fully correct and idiomatic. Sentence 2 is awkward, and not something a native spoeaker would say or write. The form "Keep X from " is generally valld, adn "keep" here means "prevent".
The form "Make X not " works for some verbs but not others. The negative form (with not) is in some cases more awkward than the positive form.
I want to make John fight. (This is fully natural.)
I want to make John not fight. (This is slightly awkward.)
I want to make everyone not fight. (This is rather more awkward, and should be rephrased.)
I don't know any good rule for when this form works well, and when it does not. When "make ... not" is akweard, a rephrasign with "prevent" often works better.
