Yes, you can pray for Tahajud in Ramadan.
During Ramadan, Muslims do many many things. For one they pray taraweeh at night and some even pray al-qeyam (tahajud) in the middle of the night. They fast the month of Ramadan, read the full Quran, be kind, give money, etc;.
Every night during the month of Ramadan Muslims pray taraweeh. Some pray it in 8 rakaats and other pray in 10 that is leaving out the 3 shaafa and witr. In the taraweeh they read or like the Imam recites a juz every night and at the end says a dua. In the last 10 days of Ramadan, the Muslims pray along with taraweeh qeyam al-layl (tahajud). It is just like the taraweeh but it is in the middle of the night when the world is quiet and people go to sleep.
I don't know what tahjhad means but it sure sounds like tahajud. Tahajud is the prayer that Muslims pray in the last quarter of the night in Ramadan. Usually, it starts around 3 and ends right before fajr and suhoor time. In some mosques in the US, the Imam, while praying tahajud and everyone is praying behind him, there are people cooking suhoor for the Muslims to eat. Very fun nights, I've been to them and helped out.
yes Muslims try to do it during Ramadan because that was what prophet Mohammed did during Ramadan he and gabriel were reading whole of the Qur'an to each other. and now Muslims try to do the same either by themselves or with a group of friends
