Sorry to say, while I see some dark spots that could be insects in your photos, I cannot see them clearly enough to tell what they may be. If you could get a clear, close-up high-quality photo they may be able to be identified. On the encouraging side, I also do not see a lot of  insect damage on the plants, and they appear to be healthy. Insects on plants are not always something that needs to be gotten rid of as the plants may be able to support the insects and not have extensive damage to the plant or the fruit. For further information on growing tomatoes and some of the common insects found on them see the following bulletins. You may be able to identify your insects from the pictures here.
