I know that a Boolean lattice must be distributive.
But what with these lattices? Are these distributive?

How to recognize which lattices are distributive or not only by looking on their diagrams? Is it even possible?

This question appears to be off-topic. The users who voted to close gave this specific reason:
There is of course the classic criterion of excluded lattices. A lattice is distributive if does not contain either $M_3$ or $N_5$ (see here for definitions). An easier criterion to check for large lattices is Birkhoff's two chain theorem: if a lattice is generated by two chains, then it is distributive. (The converse is not true.) You can find this in Birkhoff's book Lattice Theory.
