Not sure if these are things to be overly concerned about or not. All this is new to me this year and I have a few leaves and plants I have questions/concerns about. Could you please give me some advice?

As you can see lots of white spots on zucchini and squash leaves , there are also some white spots on the cucumber leaves. Also, my tomatoes have a bad case of curled leaves. Any advice on some identification of the problems and possible cures would be greatly appreciated.
