If so: When? Are there ways (or machines) to increase the amount of gravity (however slightly) so that it would be more conducive to Earthling inhabitants?

Hypothetically, if it were inhabited, what sort of post-terraforming problems could you foresee?

I think there will be large bases on the moon, but not any terraforming. The moon is just too impractical to use as a new permanent home. We will definitely exploit its resources, maybe to product space colonies and solar power satellites. Mars would be more of a candidate for colonization and terraforming. Venus would be a long shot, but if we could speed up its rotation to match something close to Earth's and find a way to convert its poisonous and crushing atmosphere, that might just be possible.

Actually, it is possible, but not that practical to terraform the moon. The moon has gravity (not that much) which, if I'm correct, is half of that of Mars. The moon is one of the biggest moons in the Solar System.
The atmosphere would probably fade away after 500,000+ years, but it would be cool. Mars would also lose its atmosphere after maybe 2-3 million years, but is probably more realistic. The best one to hold one would be Venus, if we could restart the core, speed up the rotation, and take away the poisonous atmosphere (by the way, Mars has the same atmosphere as Venus. It just doesn't have a thick atmosphere like Venus').
The moon itself does not have a magnetic field. But I think that (I'm not sure) that the atmosphere would be metastable, due to the fact that the Moon is held by Earth's gravitational pull.
The solar winds would erode it yes, but the atmosphere when it erodes would most likely get pulled back to Earth.

Mars is probably the best endeavour in the future anyways.

I hope that in 1+ billion years that humans will be able to move the planet to a better distance, and later transport it to another star system...

Add: Also, in response to the first comment, energy would not start a magnetic field. You would have to actually heat up the core to the point of liquefaction, and that wouldn't be the best way either. However, Mars and Venus also lack magnetic fields, and that poses the same problem as the Moon.
One suggestion is to place fusion reactors on them and use them to power supermagnets to retain a psuedofield.
We think with Venus, however, that if we get rid of the clouds and speed up the orbit, it will start the core up again, and produce its own dynamo effect.
Also, pressure?
Pressure is the amount of matter in one space.
For a smaller body, obviously, less atmosphere is needed to achieve the same amount of pressure we have on Earth. For the Moon, I would think we would need about half the amount we need on Earth.
Add2:
In response to the magnetic field, Venus has no magnetic field, yet it retains a stable atmosphere. The Earth at points loses its magnetic field (Pole Shift Theory) and still functions. So, yeah.
Add3: Pressure is how much mass is over each cm3.
You wouldn't need MORE gas, because the moon is smaller.
The moon could retain a stable water cycle for quite some time.

Unlikely to ever be terraformed.  You could put an atmosphere on it, but you'd need about 6x as much air per square meter as Earth to get the same pressure at the bottom, and it would leak away in about a million years.

It would be much easier and more productive to terraform Mars.

Post-terraforming issues:  an atmosphere thick enough to have good pressure would have a greater greenhouse effect than Earth.  This would create issues with the water cycle and a bunch of other things.

Terraforming the moon in the sense of fostering a breathable non-contained atmosphere is not realistic. The gravity of the moon is too weak to retain an atmosphere.

Terraforming Mars, while a monumental undertaking, is imaginable in the distant future. This all being said, I do hope that we can have nearly sustainable biodomes or underground enclosures on the moon to support long-term habitation.

The effects of gravity can be approximated via centrifuge for a period of some hours per day to maintain bone density, etc...

KEEP STUDYING SCIENCE!!!!

No.
Why would one want to terraform the moon?
It is rich in its own minerals, (which we one day might learn to harvest), but nothing else we, as a human species, would (or could) want or need.
There isn't enough gravity there to hold on to an atmosphere, anyway...
There is no such thing as a machine to 'increase gravity'.
Gravity is a function of mass... And the moon just doesn't possess that mass.
Interesting question, I'll give you THAT!
Here, have a star!

no!
the moon doesn't have a magnetic field strong enough to protect the atmosphere we'd build on the moon.

the sun's charged particles (solar wind) would rip away any atmosphere we built. We wouldn't be able to maintain enough atmosphere needed to have the pressure we have here on earth. (unless we used something besides nitrogen and oxygen)

we'd have to pump the core full of energy in order to raise the fields.

that is VERY difficult, hasn't been done yet, and would require a HUGE amount of energy.

energy better used on other endeavors.

a million) The moon does supply off easy. you're only taking it out of context and being redundant. 2) The Greeks had 3 words for heaven, one replaced into the sky, the different replaced into area, and the third replaced into heaven the place God (or the spirits) stay. i don't have time top now to look it up, yet your argument is redundant. to boot, with regard to the 1st factor, observe that he first mentions the solar being darkened and then the moon does not supply off easy. that's precisely what a scientist could say. If the solar is darkened, the moon won't supply off easy, using fact the moon gets its easy from the solar.

I don´t think so, mainly because the moon doesn´t have an atmosphere.

no there is no atmosphere to hold air in
