No - Like black holes, white holes have properties like mass, charge, and angular momentum. Consequently a white hole will attract matter like any other mass. However any objects falling towards a white hole would never actually reach the white hole's event horizon, as it is the reverse of a black hole. In example, while a black hole can be entered from the outside, nothing, including light, has the ability to escape. Conversely while a white hole attracts matter, nothing, including light, has the ability to enter from the outside (e.g. matter and light have the ability to escape).
Note: The prevailing hypothesis is that there are no lone white holes. Rather a white hole, in general relativity, is a hypothetical region of SpaceTime which appear in the theory of eternal black holes. In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past. However, this region does not exist for black holes that have formed through gravitational collapse, nor are there any known physical processes through which a white hole could be formed.
Yes, a white hole. It throws stuff out instead of sucking it in.
No the singularity is at the core of the black hole.
If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.
Into the black hole's singularity.
There is no "behind" a black hole. A black hole is not a circular disk. The event horizon is spherical, with a singularity at the center. That singularity is an infinitely dense point.

No, they are not the same. A singularity would be inside a black hole.
We do not know how the universe began, or what the exact sequence of events were.

A white dwarf is a white hot solid ball of nickel-iron alloy, a black hole is an infinitesimal singularity of infinite density surrounded by total emptiness.

Into the black hole's singularity.
A singularity is at the centre of a black hole.
Not exactly. The singularity is in the center of the black hole. Somewhat like a peach pit is in the center of the peach but it isn't the peach but part of it.

All black holes have a singularity at their center. A singularity in a black hole is a location where the density of matter is infinite, at such a location physics equations give incomprehensible nonsense answers. (singularities occur in pure mathematics also, where for various reasons usable answers cannot be obtained from the equations: e.g. singular matrices)in Static and Charged black holes this singularity is an infinitesimal point.in Rotating black holes this singularity is a rapidly spinning ring.
