Likely a modern combination of Ariana and Nelly.
Arianelly is a modern American coinage, likely created by blending the popular name Ariana (meaning 'most holy') with the suffix or name Nelly (often a diminutive of Helen, meaning 'bright' or 'shining'). As a contemporary invention, it does not have a singular ancient etymology but carries the combined weight of its components.
