I planted a dwarf calamondin tree in my backyard, and after about two years it sprouted a branch with very oversized leaves. Now this branch has fruit the size of lemons. It is planted between a lemon and a lime on either side. Did they somehow cross? an anyone tell me what's going with my tree?

You most likely have a branch growing from the root stock.
The Calamondin is grafted onto the hardy root stock of a citrus, which may be a sour orange variety.
Suckers that grow from the root stock should be pruned away as soon as they appear.
