yes
Gravity is greater between objects with large masses than between objects with small masses.
Yes, if the objects are side by side or at least in identical gravitational fields.
If the objects are the same distance apart (center to center), then the gravitational force between two less massive objects will be less than the gravitational force between two more massive objects.
The gravitational force between 2 objects depends on the masses of the objects and the distance between them. Links are provided. Newton's Law says, Force = Gravitational constant x mass of 1st object x mass of 2nd object / distance squared. F=Gm1m2 / d2 Where G=6.672 x10-11 Nm2/kg2 What this means in plain English is that the greater masses pull more on each other more than smaller masses, and the force decreases exponentially as distance increases.

More massive objects fall faster than less massive objects.

Close to large masses, time elapses more slowly. For example, on the surface of the Earth, time elapses a tiny bit slower than in outer space. In the case of more massive and dense objects, such as neutron stars, the effects are more drastic.Rotating masses produce additional effects.

The question "Do things with larger masses have larger velocities?", by itself, is meaningless, as you did not provide enough information. Things with larger masses do require more force to accelerate them than things with smaller masses. Things with larger masses do have more kinetic energy than things with smaller masses for the same velocity.
Positively charged objects have more protons than electrons. Negatively charged objects have more electrons than protons.
Some objects are more dense than others due either to the mass of the particles in the material, the atomic number or how closely the particles are packed together. For example, lead, has a high density because its particles have a very high mass. But a material like polystyrene, doesn't have a high density as the particles are spaced far apart and they have a low mass value.
They're identical masses.
Nearsighted people can see objects that are close more clearly than objects that are far away.
