Can two spells with AOEs intersect each other?

If my Triton character casts Wall of Water and my friend who is a Warlock casts Hunger of Hadar, can both of these spells intersect one another? My DM does not know to how to respond to this question. Both spell descriptions say

centered at a point you can see within range

I was thinking the warlock could cast the wall at some place then I cast my wall at a point next to the wall so they both intersect. Would that work? Also what about both walls being casted at the same point? Such as the warlock holding an action to cast it on the tree, then when I cast my wall at the same tree both of our spells would come out at the same time at the same area. Can this work?
