Answer:
The 1st, 4th, 5th, and 6th in my opinion.
Explanation:
The first one everyone should know, the freedom of speech, press, religion, petition, and assembly. The 4th one is that you can't be searched without a warrant, the 5th one being the right to keep silent, and the 6th one being the right to a fair and speedy trial. These three are very much useful, especially if you get in trouble with the police then you should know what your rights are.
