If a junction box is part of an electrical conduit system then it is required to be bonded so as to make the whole electrical conduit system continuously conductive.
No, just make sure the connections inside are tight and placed under a wire nut and taped up. The junction box must have a lid and it must be assessable at all times.
Can lights have a junction box attached to them. So yes.
Junction box labeling is required by Code (NEC) on boxes containing fire alarm circuits and circuits fed from emergency power panels backed up by generators. However, it is a good trade practice to always label your j-box covers with the circuit voltage and circuit numbers.

A 240 volt wire is the insulation factor of the wire. If you mean a 240 supply source from a distribution panel to a junction box then the answer is yes. You have to keep in mind that the box has to be accessible, meaning that you can get to the box to check the splice within the box. Don't bury the junction box behind the wall board.
You can use the junction box to send power outside to another building as long as you do not overload the circuit. Other than that there is no real benefit.
The area of a home has nothing to do with wear a junction box is placed. A junction box is placed wear a junction box is needed to split a circuit. any splice SHALL be in a junction box a junction box SHALL be accessable
Junction box for what? Do you mean a sub panel?

Can lights have a junction box attached to them. So yes.
A junction box is a container that holds electrical connections. The idea of a junction box is usually to keep wires safe, secure and free of dust, dirt and damp. A junction box is usually built within the layers of a wall so that all wires are concealed and the build looks neat and tidy.
No, the receptacle needs the screws in place to complete the bond between the metal component of the receptacle to the metal component in the receptacle's junction box. This bond is entirely separate from the grounding of the receptacle.

A junction box needs to be weatherproof if it is located outside. These junction boxes always need to be weatherproof since they are constantly exposed to rain and the elements.

Removal of an access panels from an electrical junction box depends on the type of junction box in question. Regardless of type, the first step in the removal should be the cutting off of the power main to the box itself.
No <<>> The NO answer above pertains to a metallic or PVC conduit system. In home wiring, with the type of wire being used it would be near impossible to drag a cable through a switch or receptacle junction box without cutting the cable. Once this cable is cut, the grounds have to be spliced together and this ground wire is then required by code to be grounded to the box.
