If u have a grater and a sieve or a clean cloth to squeeze the grated apple, its more effective than any juicer.
I really don't know, but I've been drinking apple juice from a juicer for literally decades, and no ill effects.
Electric juicers run on electricity and one will not get tired when one extracts juice from fruits and veggies. However, juice extractors run on man power, so one may get tired after squeezing juice from fruits for some time.
Breville - Juice Fountain Plus Electric Juicer is the best mixer for Bacardi apple.
orange have more juice because is bigger than the lemon
No, you can't juice things with oil in them, it can ruin the juicer

Yes, if you are blending or juicing these things fresh yourself. All three of these fresh ingredients can be put through a juicer, then drunk without heating it in any way.
Juicer is a device used in making juice
yes
Not every juicer can juice wheatgrass. You need one that can chop up the blades of grass. A centrifugal type of juicer won't do that. A masticating or triturating juicer will. See the link for some good wheatgrass juicers.
Personal opinion: The quality of juice it produces. Some juicers leave the drinks a bot "gritty", a quality juicer blends perfectly, without the kids noticing you just loaded the juice with their most hated veggies!
You can use a juice seed to make drinks with the juicer.
