"Are Christians pro Love, Grace and Kindness?"
That is the ideal. But the premise of Christianity is that all humans have been corrupted away from God's ideal. That is why we all need a Saviour. Sanctification (moving towards God's ideal, away from the corruption) is a process. Individual Christians are at different stages of that process. Sincere Christians are moving towards perfect "Love, Grace and Kindness", but none of us are there yet.
"Why do wage wars if you are honest?"
I don't "wage wars"
"Are you honest that nobody should/can judge the others?"
God has the right to judge everybody. Christians have the right to inform about God's judgements, but we don't have the right to judge on our own behalf. Sin is an offence against God, not us.
"Do you agree with Jesus that let Caesar's works be given to him and religion is different from politics?"
Christianity is not an administrative covenant. It deals with individuals, not governments. Christians are taught to pursue peaceful coexistence with those around us (without offending God); including our government.
"Faith is enough, do you agree in that?"
A Christian is someone who has sincerely surrendered ownership of their life to Christ as a faith response to His gospel. If there is no response to the faith, then the faith is pointless.
