> 1-How long will the other bees feed the queens in there cages?
Years.
> 2- What will happen if you add more queens latter on without removing the old ones? Will they just stop feeding the new ones? or...
They will kill the old ones and feed the new ones.
> 3-Could I just take a piece of 3/4 lumber the size of the inside of a frame drill about 50 1-1/2"holes all over and than sandwich the wood with queen separators and mount it all in a frame to have 50 or so queen jail cells were the workers can get in an feed them???
Sure. Or use JZBZ cages and something like this:

It will hold about 150 queens or so...
>4-What is the easiest way to get all the queens mated?
Separate mating nucs for each queen. Cage them AFTER they are mated.
> Can you just let one queen loose at a time?
No.
> or do you have to build a matting nuc with 2 frame nuc's all separated in one box?
If you want 150 queens you need about 200 mating nucs each with a queen cell...
