Yes. There are five orbitals, which is of the nature of the D orbital, as there are three p orbitals and one S orbital. Each orbital holds two electrons, so the D orbitals have the capability to hold 10 electrons
If you take a look at the magnetic quantum numbers for the d, they are -2, -1, 0, +1, +2, which are 5 in total. Each orbital is able to hold 2 electrons, therefore the d-orbital can hold a total of 10 electrons.
