weaker
Weaker.
yes
All of them do. There's no planet where the gravity is the same as on Earth.
Earth has weaker gravity than the sun bu stronger gravity than the moon.
It isn't clear what you mean with "stronger or weaker". Neptune's gravity is stronger than that of Earth, if that's what you mean, since Neptune has a larger mass.
it has weaker gravity than Earth
It has a gravity which is 0.4 times that of the Earth's.
Venus has weaker gravity than Earth.
Weaker. The gravity on the surface of Venus is about 8.87 meters per square second; for comparison, on Earth, the gravity is about 9.82 meters per square second.
Pluto has a weaker gravity than Earth. In fact, Pluto has a weaker gravity than Earth's moon.

It has much weaker gravity.
Weaker as it is smaller.
