help identifying plants and vartiants

We have many difernet plants growing on the garden probably from a birdseed bags of chicory and lettuce seeds, the problem is identifying the variants and which are edible

first set of photos, i believe these are from the same kind of plant

second set of photos, they look similar, but much narrow leaves and long leave steams, we have a couple of varieties in between

third set of photos, these ones i though were latuca but not sure which, they have soft spikes,or hairs on the leaves, they taste less bitter than the others, someone told me they were edible, we boil them sometimes, are these really edible?

and another one that looks like similar to the first two, i think they are some kind of chicory as they have a very bitter taste and i think are developing pink flowers (i have to walk around agian to see if they already bloom)
