About as close as we can get to an ID on these is your 3rd and 5th pictures are some sort of grape or paste tomato. If they're small, they'll be yummy little sweet grape tomatoes. If they get larger, say 2 or 3in. long they will be paste tomatoes. Still good for salads but mainly grown for sauce and paste.
The last picture shows a round tomato. That one will be a slicer of some sort. Can't tell you much more than that until it is ripe. Show us more pictures then.
The marks on that leaf look like maybe there was water sitting on the leaves when the sun was shining on it. Burn marks. Nothing to worry about but if you don't like the look of it, just remove the leaf. Doesn't look like any kind of disease to me.
Next year, buy some seeds and label your plants so you'll know what they are. Even if you plant seeds from a grocery store tomato, you won't necessarily get all the same kind. Oh, and remember One Plant per Pot!!
