No

No, because some of them are translated to the left, right, up or down from the parent graph and are no more symmetric to the $y$-axis. Only the following absolute value functions are even: $$y=a|x|$$ An absolute value function $y=a|x+b|+c$ is always symmetrical with respect to the line $x=-b$. The function is even when $b=0$.
