Is it recommended to take the names of martyrs of Karbala and infallibles along with the names of other momineens in namaze shab? Because in Majlis we often hear the last will of imam Hussain to his sister Zainab (s.a.) to remember him in salatul layl.

Yes you can take the name of shuhada e kerbala in namaz e shabb. But as we are ordered/recommended to pray for the forgiveness of momineen and martyrs of Kerbala doesn't need any maghfirat therefore we should dua for the increase of their darajaat. We also must not forget our close blood relatives and momineen

In many cultures, there are superstitions/rituals carried out (which have no Islamic basis) to prevent bad things from happening/to make sure something good happens, for example, in many cultures, when someone leaves to go to the airport, water is thrown on the car they're going in to ”make sure” they have a safe flight, are such rituals/superstitions a form of Shirk?

No none of our marja says it's shirk but we should follow what has been taught to us from masoomeen like giving sadqa(matching your financial status), reciting aayat al kursi, 4 qul, tasbeehat e arbaa, salwat, to leave house with wuzu
