i've heard about this and would like to know if it's true.

You are referring to the phenomenon of "odd sympathy," which causes two pendulums to swing in perfect opposition. The pendulums need to be mounted not just near each other, but actually on the same beam. The beam moves imperceptibly, eventually manipulating the pendulums into the opposed synchronization. My reference article doesn't say, but I assume that the two pendulums do need to have the same length so that they'll have the same period.

If their periods were exactly the same, then they would never appear to synchronize. If their periods were slightly different, then eventually they would appear to synchronize. But then they would go swing out of synch again.
Ultimately, the pendulums have no noticable effect on each other.

When the two masses pass each other they will be attracted to each other. If the pendulums are close enough and are the same length, this is will happen. All masses are attracted to each other, they will swing together.

I don't think it will happen.The swinging path will eventually changed to cone shape from straight line due to rotation of eatrh.
