What is true of it
D♯maj9 is D♯, F𝄪, A♯, C𝄪 and E♯ — 1, 3, 5, 7 and 9 counted from D♯.
F𝄪 and C𝄪 are double sharps, and they have to be: every letter from D♯ upwards is used once, so the 3 cannot be written any other way.
On an instrument that cannot reach all 5, the 5 and 1 go first, in that order.
The easiest of the 5 fingerings below is x60063: 3 fingers, held at the 3rd fret.
1 of them use open strings, which is what makes a shape quiet to change to.
It leaves out the 5. 6 strings cannot carry 5 notes, and the 5 is the one this chord can lose without changing what it is.
1 string stays silent.
Where its notes are on the neck
The brass dots are D♯, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
