What type of music is this?
 

I've seemed to adopted a taste for a particular type of chill electronic music, but I'm not sure what sub genre it actually is. I'm not sure if you could put all of these tracks in the same genre, but here's some of the music I've been listening to lately:

Elfsong - Eta Carinae (Celluloid Mix)

Lank & Zajac - Juice Box (Echomen Remix) - Mesmeric Records

Roman Jones & Hendrik Zoe - Casual - Romeofoxtrott Remix

Camelphat - Watergate (Life And Remix)

I would like to find more music like this, but how? What sub genre are they exactly, some form of trance I assume?

Progressive House

Yep, i would also say progressive house.

definitely progressive

Yeah, it's progressive house.

As everyone has said this sounds like the more chill end of Progressive House, I'd recommend checking out stuff that the label Anjunadeep releases.
