Both ^ and ~ themselves mean the parent.

~ followed by a number works the same as putting the same number of ~. For example, my_commit~3 is the same as my_commit~~~ which refers to the 3rd parent of my_commit.

But ^2 only makes sense for a merge commit, i.e., merge_commit^2 means the second parent of the merge_commit, merge_commit^1 is the same as merge_commit^ or merge_commit~ or merge_commit~1.

On the other hand, repetitive ^ is the same as repetitive ~. For example, ~~~ is the same as ^^^, and the same as ~3.

Some examples:
