Honor is not a particularly Christian virtue. It is mentioned biblically, but not nearly as often as other virtues we are expected to follow, particularly the most important one, Love. You haven't defined honor particularly clearly, but where your definition conflicts with Love, a Christian should be loving rather than honorable.
As for solidarity with friends and relatives, the Bible (the New Testament) explicitly says it is forbidden to favour your friends and relatives over other people. While there are certainly commands to honor those close to you ("Honor your father and mother") that does not imply that you should take their side just because they are related to you. "Honor" is not the same as the unthinking solidarity you seem to be talking about. If your father or mother do something terrible you are not expected to shield them from justice. Matthew 5:43-47:
You have heard that it was said, βLove your neighbor and hate your enemy.β But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect.
