I hate to break bad news to you, but be prepared for fighting if your rabbits aren't spayed/neutered. Generally speaking rabbits are territorial.
The good news, for the does, 100 square feet is probably enough for them (and a few more; I have heard the rule of thumb is 10 square feet per adult rabbit). There might be a little scuffle over some particular territory at first. (Especially if they are normally housed separately.) Most likely you can throw both of them in that cage at once.
As for the bucks you will get fighting! Maybe if they are young and not sexually mature (or all have been neutered); then you can put them together without major worries. BUT that only lasts until they mature, hormones kick in, and they become real rabbits. 100 square feet? They might as well be sharing a shoe box. That's territory (territory that smells of females as well). And as far as the bucks will be concerned there can be only one buck in that area.
Realistically, your super, awesome, best case, but not very likely to happen scenario is a dominant buck emerges quickly and is satisfied with the others just staying in a small portion of the pen. The more likely case is every time you toss them in together a new fight will start up. You might end up with a rotating "king of the day" without major injuries, or your bucks may mess each other up badly, or try to castrate each other, or they may end up fighting to the death.
If you really want to let them out you'd be better off giving each buck alone time in the pen (which they will probably use to mark the place up). It might be your dream to let everyone run free together. But as they say the best-laid plans of mice and men often go awry.
Perhaps you could divide the pen up into three sections and give every buck his own slice?
Oh and unless you have a decent sized yard and that pen is easily moveable, the rabbits will eat all the grass quickly (as in two or three days). If you can't move the pen, you will just be giving them exercise time. (Which is still a good deal).
