all of the parts you pictured are fairly standard and ubiquitous
there are multiple suppliers of all of them
(how did you get pictures of things you don't know what are?)
the blue three place connector may be found in the phoenix connectors
it will not be blue, but it will fit - you'll have to do research to cross reference
from the Phoenix Connector website
the ten pin double row header is likely in the Molex section
and several others
the potentiometer is there too, i just don't have a place or it right now
likely bourns
likewise the power connector
it can be frustrating finding parts in the eagle libraries
i suggest you go to a distributor website, such as digikey, mouser, newark, etc
search for comparable parts in their search systems
if you know the electrical parameter and the pwb spacing of the leads
you can find comparable parts
i like digikey as my company has an account, they're search engine is pretty good
and for historical reasons, it the one i used the most.
