Yes, it matters. The red wire is typically the live or hot wire, and the black wire is usually the neutral wire. Ensuring they are connected to the correct terminals in a circuit or appliance is crucial for safety and proper functioning.
Connect the white wire from the European oven to the white wire in the US receptacle. Connect the black wire from the European oven to the black wire in the US receptacle. Connect the green wire from the European oven to the bare wire in the US receptacle. The green wire serves as the ground wire since you don't have a separate ground wire in the US receptacle.
House wire is "line" Black & White house goes to Black & White of Timer; the "load" (e.g. Pond Pump, etc.) is connected to the Red & White. Specifically, put all 3 whites together (nut or terminal); House (source)(line) Black to Timer Black; and "load" Black to Timer Red. The Red wire is the "Timed" (switched) hot wire.
No, it does not matter which hot wire (red or black) is connected to L1 or L2 for a jet pump pressure switch in a 240V setup. The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.
You can connect the red wire from the USB cable to the red wire of the two-wire cable. The black wire from the USB cable can be connected to the black wire of the two-wire cable. As for the white and green wires from the USB cable, since the two-wire cable only has a red and black wire, you can leave the white and green wires unconnected as they are not needed in this case. Just make sure to insulate the unused wires properly to avoid any short circuits.
When setting up an electrical circuit, it is recommended to connect the black wire first before connecting the red wire.
Red normally is a live wire. However, it's just a matter of a plastic coating over the wire, and a red wire can be connected any way someone wishes to on any circuit.
Usually the red wire is the hot wire, black ground, a couple for speakers (maybe 40 & 1 for antennae.
Black Wire from photocel to hot wire(black) coming in red wire to light fixtures black wire. White wire to neutral wires all light and power source white.

The red battery wire goes on the positive + battery terminal no matter which side it is on. The black wire goes on the negative - terminal.
