how much current can they carry? Can they sustain current between 1 to 2 amps?

YES I BELIEVE THEY CAN SUSTAIN 1-2 AMPS

what determines pin-orientation of these connectors? I returned an order like these due to connection issues but pins 1+2 are reversed

Sorry couldn’t tell you without wiring info on your item. I ended up changing both sides because new female plug or male plug wasn’t compatible with old so it wasn’t a problem as long as wires matched. Sorry can’t be more help

will these carry 5AMPS current?

NO ! they'll melt down with 5amps
