Asriel is the angel (confirmed by River person).

I think the triangles symbolise the OTHER three Dreemurrs. As in Toriel, Asgore and Chara (or, possibly, Frisk).

The triangles, 2/3 are upside down. Monster souls are upside down, so it'd make sense if only two were monsters.

But then again, maybe the triangles just represent monsterkind.
