It would be helpful if you kept all this stuff in the SAME thread you originally started. You'd have to divide the ownership into small enough pieces, you would need to know the current value of whatever share you give to make sure it is below the exclusion. Further, of course, you need to make sure it is a legitimate present interest gift. Anything that puts strings on it that keeps the recipient from having full ownership and use rights form the day of the gift is NOT excludable.
Further, you ought to pay attention to several things. First the overall inheritance from this gain may not be in any of the participants best interest. If the property were to be inherited, it would be stepped up in basis to the value at the time of death. If you give it away now, the recipients will adopt the giver's basis (which presumably is pretty low).
Since you didn't bother answering any of the other questions posed in the other thread, it sounds like you really don't want an answer that's meaningful.
Go get a real estate planner or risk screwing this up.
