Can you split a ground wire from an outlet wall and use it as grounding for making a new outlet with hot and neutral wires from a different source? (like using the hot and neutral wires from the celing lights in the whole house, spliting them to make new outlet).

There is one hot & neutral line for each floors but all the floors uses one hot and neutral line for the all the lights in all the floors. Im planning of making an outlet by splitting the hot wire and neutral wire from the lights line but it doesn't have a ground wire.

If its possible would it be safe? If not, can I make a fuse or breaker box to make it work and safely.

No, the correct way is to run a new circuit (cable) from the service panel to the outlet.

You can also use a GFCI receptacle. You have to label the receptacle as not grounded if you just want to use the existing two wire circle.
