You will need to walk/run/bike a certain number of steps to hatch the egg.
Just look for a Pokemon with flame body ability and then your eggs will hatch.
It depends on the Pokemon that is inside the egg, some Pokemon need more time to hatch. But you can always use Action Replay to make eggs hatch faster.
You can't make the eggs hatch faster, but you can play Pokemon Crystal Version on the Nintendo 64 with Pokemon Stadium 2 which has an option to increase the gamespeed.
No. Legendaries can't "make eggs".

pokemon that have the abiliti magma armor cammerupt,sluga,and macargo or ar code for quick egg hatch
No sadly, they don't. I don't exactly mean by 'hatch eggs' but if you mean make eggs in the daycare centre they don't (we'll you can't clone them.) But some can hatch out off eggs like Riolu. (Devolution of Lucario)
No you cannot. Legendary Pokemon can't breed (make eggs). Not even with Ditto.
Put them in your party with Slugma/Marcargo, this pokemon's body heat will warm the egg and make it hatch faster.
It depends on the egg your hatching, but its usually around 2,000 - 5,000 steps. The fastest way to hatch it is to literally ride on your bike (: -Chii Magmar + Bike your egg will hatch within 5-10 mins.
Use a Pokemon with the ability magma armor or flame body (Slugma's ability usually)
