So far, we can only survive in bio-spheres on Mars or Europa or Eros. Due to their extreme climates, hostile atmospheres, we need some help....

Humans have survived for days at a time on the moon, and in some cases, more than a year in orbit in a space station.
But I suspect that you are referring to being able to survive without sealed environmental life support assistance.
There is nowhere that we know of at the present time that could support human life outside of Earth.
Such an environment would require (at minimum) an oxygen atmosphere and temperatures in a range conducive to not dying.
As far as we know, the development of an oxygen atmosphere requires the action of photosynthesizing plants, which would also require light, carbon dioxide and water, plus, of course plants.
While Mars may have carbon dioxide and light, there's no water that we know of at this time, the carbon dioxide is pretty thin (around 6 millibars), and there's no sign of plants or oxygen at all.
Venus also has plenty of carbon dioxide, but in that case it's a little too thick. About 95 times thicker than Earth's atmosphere. That much greenhouse gas also traps quite a bit of heat. Average temperature of 450 degrees kind of too much heat. Plus, there's a bit too much sulfuric acid and hydrogen sulfide in the atmosphere to be pleasant.
It is certainly possible that there may in fact be planets out there, somewhere, that have suitable atmospheres, maybe even ones with life and photosynthesis and oxygen atmospheres already. We just don't have any evidence for any yet.

Mars is a candidate but life support systems would be needed. There is no place in our solar system that humans can survive other than Earth withouth life support of some type.

Humans have survived for months in the internatioanl space station and for days on the moon.
Whether or not there is a planet suitable for human life that does not require various complicated life support systems is a question that has been argued for years.
Some say that only our earth , out of all of the billions and billions of planets can support human life.
Others argue that it is vey arrogant to think that only Earth out of the seemingly infinite number of planets can support human life.
If you are religious, you would tend to support the view that only planet Earth can support human life as we know it.

We removed a subject from Earth several hundred years ago for study. He was not real excited about going back to 14th century England and asked to accompany us. He landed on three other planets before settling on the Gonfrix home-world where he lived for 14 of your years. His name was Throckmorton Grendle and he did become homesick near the end.

Sustainably, none that we no of.
No nearby planets could support us -mars for instance has only about 1/1000 our atmospheric pressure and almost no oxygen (let alone water).

not only is there under-ground water that has been found on mars but the average temperature on mars at the equator is 75 degrees

statisticly there are thousands if not millions of other planets in the universe with an atmosphere similiar to ours
