Hope you've labelled them now! If you haven't got any labels, cut up an old yoghurt pot or similar and use that. If you've had to untangle them, it makes me think that they're getting a bit crowded and could do with pricking out and potting on. When you do that, replant them deeply up to level of seed leaves. The tomatoes are very frost tender, where are you thinking of growing them?
