If there are two G1 races at the same time, one with a higher purse, will the better horses run with the higher purse or will they be evenly split between the 2 races?
Assuming they are both over the same distance, you'll find that the race that comes first in the schedule file attracts the strongest field.

The opposite, if there are 2 races with the same purse but one is a G1, the other a G2, will the better horses run in the G1?
Yes, in this case, the G1 should attract a slightly stronger field. You wouldn't tend to get horses rated higher than around 128 in a G2, but in the G1 you should get horses rated up to the 140 maximum.

Or if I have a G1 with a smaller purse and a handicap/listed race with a bigger purse, will the better horses run for the money or in the G1?
The purse size doesn't make a difference. The G1 will still attract a G1 field. Listed races wouldn't tend to attract horses rated any higher than 108/110, regardless of the prize money. As for the handicap, it depends on what type of handicap it is.
