If you plant lemon trees next to orange trees or other citrus, will they cross pollinate? Or is that something that needs to be done in lab condition?

There is a possibility that they would cross pollinate but you would only see the results of that cross pollination if you planted and grew the seeds from the cross pollinated fruit. As citrus trees are not typically grown from seed, it is not normally considered an issue.
