Yes. Momentum is based entirely upon mass and velocity, as shown by the equation p=mv, where p is momentum, m is mass, and v is velocity. Since an object can still have both mass and velocity in space, it can have momentum in space.
Not unless it is hit or collides with another object during travel. As a spaceship burns fuel its mass is reduced. Burning fuel would normally increase velocity (acceleration) unless the fuel expended offsets some gravitational pull.
A spacecraft might also eject a spent rocket stage or cargo, thus reducing its mass. Another spacecraft might match velocity with it, and attach itself with magnetic grappling hooks or whatever.
Velocity is a vector, so any change in direction represents an acceleration. A collision with another object should result in a change in velocity.
When an object is still it has no momentum. That is, the momentum is zero.
Momentum can be transferred from one object to another. Momentum can be slowed by an intervening object. Momentum can be hastened by an intervening object.
momentum is equal to the mass of an object x velocity of an object
The product of an object's mass and velocity is called it's momentum. It is mostly called it's linear momentum to differentiate from the term angular momentum.
Momentum is related to velocity and mass. When an object's velocity is zero relative to its surroundings, it has no momentum. Therefore it is untrue to say that an object never looses its momentum.

You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
No, it cannot. In the case of an object moving in the free space (no forces acting on the object) the energy consists of only the kinetic energy which is proportional to squared momentum. Thus, if the object has a momentum it has an energy to. Basically an object possesses some energy in any kind of time, and it might happen that the energy is zero. It doesn't mean that it has no energy. It means that the object has energy equals zero (which is not the same).
Momentum depends on the mass and the velocity of an object. In physics, P=mv, momentum equals mass times velocity.
The momentum of a moving object is (mass of the object) multiplied by (speed of the object). Neither of those numbers is affected by where you are, whether on a planet, on a moon, or in space. Mass times speed equals momentum.
Momentum. If an object has constant velocity, the object will move because it has momentum. Momentum tends to stay the same unless changed by a force.
