1. Are you crazy?

4. Love and peace!
5. Death and distruction!
6. Oh momma.

1. Kimi wa aho/baka ka? (I think aho/baka would translate to more like stupid though...)

2. Watashi te sonna ni baka?

3. Ima choto kanngaete mitara, korete keko kowai.

4. Ai to heiwa!

5. Shi to hakai

Sorry I couldn't think of the last to and the ones I did translate were as close as I could get to everything.
