If the masses of two objects are each halved, and the distance between them doesn't change, then the mutual gravitational forces of attraction between them are reduced to 1/4 of their original magnitude.
The effect of dubling the massesa and halving the distance is to increase the gravitational force by a factor of 16.
I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
The gravitational force will become 4 times..
Then it takes twice as much time, or half as much time, respectively, to cover it, provided that the speed never changes.
The force will increase fourfold.

No, it is increased. If the separation is halved, the attraction is quadrupled.

The one with the larger mass would pull the halved mass one toward it
The forces in each direction are quadrupled.
The force of gravity is inversely proportional to the square of the distance. That is, if the distance is halved (reduced by a factor of 2), the force will increase by a factor of 22 = 4. Another example: if the distance is increased by a factor of 10, the force will be reduced by a factor of 102 = 100.
45 cannot be halved by 10.
