1.Tawheed ul-Uluhiyyah/Ibaadah
(Tawheed of Worship)
Tawheed of Worship means that all acts of worship belong to Allah alone, and no one else. All acts of worship Ibadah are purely and sincerely for Allah, not for idols, not for any Prophet, not for any Aulia Allah ,not for the universe, not for anything except the one Allah.
2. Tawheed-al-Rubbubiyyah
(Tawheed of Lordship)
Tawheed of Lordship means that you believe that there is only one God, namely Allah, and that there are no other gods or goddesses. All form of Ibadah and Worship is only for Allah.It also means that all power, creation, and such things belong to Allah alone, for instance Allah alone is the creator of everything we see around us, and it is he who is in full control of them, and it is he who controls life and death and all such matters, and not anyone including our money/Position/ materialistic resources/worldpowers or any human or devine help other than Allah else.
3. Tawheed-al-Asmaat wa-Sifaat
(Tawheed of Allah's names and Attributes).
Tawheed al-Asmaat wa-Sifaat is the Tawheed of Allah's unique and exclusive Names and Attributes, this means a Muslim affirms a Name of Allah, and affirms that this Name is unique and exclusive to Allah alone, not for anyone else, and not for anyone else to be named with.
For example one of Allah's names is the All Knowing, this Name is unique for him alone because Allah is the only one who is All Knowing, and perfect in his knowledge, there is no created being who has such an attribute. The same applies to all of Allah's names, they are unique for him alone, and not for others.
May Allah guide us.
