Oil is pretty much oil. As long as the weight is right 10W-40 for example it doesn't matter in the least who makes. It.

Yes, you can. (And, Honda sales will thank you very much for doing so. Especially at their ridiculous pricing!)

Likely yes- but actual oil and actual engine information needed. Honda Motorcycle oils for specific motorcycles may have zinc additives that help the motorcycle clutch and transmission gears wear-- but will 'poison/foul' a cars catalytic convertors. The low friction car oil that glazes motorcycle wet clutch resulting in a $400.00 clutch job is balanced by the motorcycle oil that results in failed emissions tests and a $1200.00 cat and sensor replacement job on car.

OMG! NO! That would be disastrous.
