Yes. Every Nafilah Prayer is usually two Rak'ats like Fajr Prayer, but Nafilah Prayer can be performed with reciting Sura Al-Hamd only with out other Sura, although it is better to recite another Sura in Nafilah, while it is obligatory in Fajr Prayers to recite another Sura after Sura Al-Hamd.
Nafilah Prayer can be recited while sitting with out illness and even while walking intentionally, and when it is recited while walking, no need to face Qibla. There are other facilities in Nafilah Prayers.
Wassalam.
