Menexenus is just one long speech, a good speech I presume but not very philsophically interesting. Maybe Menexenus together with Symposium can give insight into Plato´s attitude toward women ahead of the female guardians in Republic. >>24840992 explained why the other dialogues can be skipped.

The dialogues have no set order yes, but there seems to be a consenus that the collections in tetralogies 6 and 7 should be read later. I guess I should have specified that my pic is the collection of dialogues that can be put before Republic. The order of them is not very important except for some like thematic orderings like the trial of Socrates, Gorgias-Protagoras and Alcibiades-Symposium-Phaedrus.
