Are we at all able to change our names?

I'm sorry if what I said above sounds rude, but is it possible to change your name? I'm changing most of my Social Media profiles to Jer the Hedgehog, because I'm not an Arle Nadja fan as much anymore.

To change your name you can DM a moderator in the Message Board or in Discord.
I'm not sure but name changing should be possible in Talk to the Moderators, but they haven't said anything about that, and the forum information just says to use it for reporting behaviour. So I guess you can't.
For now, DM a moderator

You need to specifically DM an administrator (the users with purple names), I do not believe moderators have the ability to change your username. Posting in Talk to the Moderators is also a good alternative!
