How fast will the iPhone charge with the MagSafe at 15w? Is 15w enough to charge the iPhone from 0 to 50% in 30 minutes? Also, what adapter do I need for it? Is a 20w adapter suffice? If I go higher on watts for an adapter, will it charge at a faster rate or will the iPhone just pull in what it can no matter how high the wattage is?

It is hardly charging with my Anker 20w or 18w brick.
And it charges very slowly with my 30w RAVPower brick.
The MagSafe only gets warm without charging.

I suspect you HAVE to use Apple brick to make it work properly.

That would be a bummer

Have one arriving tomorrow. I'll compare it to the 18w Anker I used tonight.
