Yes as long as you use an approved splice, such as a wire-nut.
Look on the box or bag that the wire nuts came in, there you will find all of the combinations of wire sizes that can be connected together under one nut.
Depending on the size of the wire, you can use wire-nuts for the smaller gauges Do not twist solid and stranded wire together when you use wire-nuts. Just lay the exposed conductor side by side and apply the wire-nut. If you wrap the two wires together, it was found, some connections have pulled apart due to the wire-nut not biting into the solid wire as the stranded wire was wrapped around it. Split bolts for the larger sizes and Allen key wire lugs bolted together for big size wire.
You should have black (hot), white (neutral) and bare wire (ground) coming into junction box. The two circuits leaving the box should use the same size wire which should be sized for the branch breaker and you just use a wire-nut to connect all black wires together, another wire-nut to connect all white wires and a third wire-nut to connect together all ground wires. Since you are splitting into two branches, all wire-nuts should have three wires of the same color.
Tie all the white wires together under a wire nut and push them back in the box. Tie the black incoming power wire and outgoing power wire, if there is one, together under a wire nut with a black wire pigtail. Connect this pigtail to one screw on each light switch. Connect the black wire going up to the lights to the appropriate switch you wish to use to control that light.
High Heat Porcelain Wire Connectors are very safe.

The electrical terminology for this device is a wire nut. If the two #10 wires are solid, twist the two stripped ends together with pliers and apply the nut to the wire ends. If the two # 10 wires are stranded lay the two stripped ends parallel to each other and apply the wire nut. Do not twist the stranded wires together.
Connect the ground wire to the metal box.

Leaving any exposed bare wiring can lead to short circuit and breaker tripping. Most of the times wires in junction boxes are jammed into the back of the box. This is to allow for a device such as a switch or receptacle to be installed. Leaving exposed wire showing below the wire nut could allow contact with other exposed wires or it could come in contact with the bare ground wire which is also jammed in there. Good workmanship should prevail, only strip as much wire as needed to twist the wires together. Then install the wire nut. The skirt of the wire nut should project down over the insulation of the wire by a quarter of an inch. If it does not use a larger wire nut. This will provide full insulation protection to the wires in the junction box.

Yes, you can use urethane paint on porcelain mugs.

The most common way of making an electrical connection is with a device called a wire nut. Solid wire connections should be twisted together with a pair of pliers before installing the wire nut to hold the splice tight. Twisting stranded wire together with a pair of pliers does not allow the wire nut to grip the wires as tight as it should. Stranded wire should be held together side by side (in parallel) and let the wire nut twist the wires together to make a solid splice connection.

Sure. Just cap it off with a wire nut.
