comment Is $d_1(x,y):= x^2-y^2$ a metrics on $\mathbb{R}$?
@TAN easier to check symmetry, you should have $d_1(x,y) = d_1(y,x)$ for any choice of $x,y$ -- is this really true?

comment Biased Asymmetric Random Walk
not clear you can reuse the same result. This walk is biased, so larger p means you will have drift; also skipping one may be a problem -- i.e. you can reach -1, and then skip over to 1 if $n<0$.
