"so now my questions...should i feed her?"
That's up to you. If you're temps are alright for digesting, she can eat. If you do decide to feed her, wait until after she sheds. Then offer her "small" meals. Probably 1/4 her usual size. You can offer these meals, if she'll take them, once a week. Stop offering her food 4 to 6 weeks before her due date.
"also if shes in post ovulation do i need to leave my males in with her still?"
If the males have "completely" lost interest, you can remove them.
"i had 3 males in with her all normals..2 at a time though...they all had been with her and showed interest and copulation....now NONE of them have any interest at all with her...does this mean they know job is done?"
If they've all lost interest, it's a VERY good sign. Sounds like their job is done.
"also one male just shed and ate..the other 2 are in shed right now as the same time as the female and they dont wanna eat.."
Wait for them to shed, then offer them food.
"also since the been together temps are about 84 or so..is the temps ok that high while breeding?"
I keep the temps higher for breeding. I'll keep the warm end between 80 and 82 degrees. I slowly raise the hot spot to 94 degrees. I keep the snake room between 80 and 85. My boas seem to "prefer" it warmer. My boas will "stop breeding" if the temps on the cool end drop to 78 degrees.
"any suggestions on all this please help me out...i dont wanna slug out"
It's hard to say what can happen. I do know what I observed last year. I had 6 litters born. There were 2 perfect litters. These were in the highest cages and were the "warmest". I had 2 litters that had 1 and 2 slugs. One of the litters was in a high cage. The one with 2 slugs was the second down from the top. I had another litter that had 9 babies and 7 slugs. This boa was in the bottom cage. I believe the temps in that cage might have been a bit cooler. Since heat rises and the ones in the higher cages were probably warmer. I had one last litter. There were 4 babies and 14 slugs. Breeding this girl was an "after thought". I put a male in with her that had just come off another female. This girl ovulated a few days later. I think the reason for her high slug count was because I put the male in later and from just having come off another female. The other female he bred is the one that had 2 slugs.
From the 6 litters I had last year, I found that warmer temps were better for gestation. I plan on keeping my gravid/pregnant females in the higher cages, so they get the maximum amount of heat.
