What kind of connector is this? (multiple pics)

[Kobur]

I am trying to be sure I am understanding what people are talking about when they talk about a particular type of connector, so I someone would help me ID these connectors I would appreciate it lots. In each of these there is a T-connector or Dean's style connector. I know that one. I can also identify properly Traxxas, Tamiya and EC3 style connectors. So in each of these images, please just ignore the T-/Dean's connector. Thanks in advance

First: A Connector I Can't ID:


Second: What I think is maybe a "J" connector??? (The black one; I know the red one is a T-connector or Dean's style connector.)


A closer look at the Second:


Third: Is this a JST?
