…
Also, does wine and bread not on the altar during the consecration get turned into Jesus as well?..
I’ll address just this last part.

The priest must have the “intention to consecrate.” But how is that intention stated?
Whatever elements (bread/wine) are on the corporal during the consecration become the Body and Blood. It is a “given” that the priest has the intent to consecrate whatever is on the corporal (presuming that he has the intent to celebrate a valid Mass) and likewise not-to-consecrate whatever is not on the corporal. Note that the distinction deals with the corporal and not the altar.
That might seem a little obvious, but let me explain by examples. If there is an extra host that falls out during the offertory, and lands on the altar but the priest isn’t aware of it, then it’s not consecrated. If the priest keeps extra hosts on the altar (perhaps to add them at the offertory if needed) but does not place them on the corporal, they are not consecrated.
Any bread/wine which is not on the corporal during the consecration is consecrated ONLY if the priest specifically intends to do so.
If the priest doesn’t have enough room on the corporal to fit all the vessels, the right thing to do is to add another corporal (or more) to make one large corporal. However, if he skips the corporal and still places the vessels on the altar, they are consecrated only if he intends to consecrate them. This might seem like a given, but it’s not. No doubt, some readers are thinking “since he put them on the altar, of course he has the intent to consecrate them” But that’s not how the Church defines it. The presumed intent applies only to what is on the corporal, not the altar.
I’m willing to bet that some are asking “how can he put hosts on the altar but not have the intent to consecrate?” It happens…
Some examples:
A priest might accidentally drop a host on the altar either at the offertory or even before Mass–or the same might happen to pieces of an unconsecrated host.
I once said Mass as a visitor where the pastor kept a supply of unconsecrated hosts on the altar “hidden” by the missal stand (in a little plastic deli container). I didn’t even know they were there until I’d been saying Mass for a few days. Keeping hosts stored in the altar like that is not a very sound thing to do; so “don’t try this at home folks!”
On the other extreme:
If the priest has the specific intention to consecrate bread/wine which is not even on the altar, so long as it’s present at Mass (ie, not in the other room, or something like that) then it’s likewise consecrated. A priest in a situation like that would have to be very explicit/specific in his intent though.
