Q-1 Buoyancy:
Buoyancy is the ability of an object to float in a given fluid.
Upthrust:
Upthrust is the upward force exerted by a fluid on an object partially or fully immersed in the fluid
Q-2 The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G). The relation between G and g is not proportional.

Answer:
answer1
Main Difference – Buoyancy vs Upthrust
The two terms Buoyancy and Upthrust are frequently used in fundamental physics. Even though some people use them interchangeably, they have different and particular meanings. Buoyancy is the ability of an object to float in a fluid whereas upthrust is a force exerted on an object by a fluid within which the object is submerged. Simply, buoyancy is just a tendency of an object to rise in a given fluid when it is submerged. But upthrust is the buoyant force exerted on the object by the fluid. This is the main difference between buoyancy and upthrust.
answer2
The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G). The relation between G and g is not proportional.
