What are these coaxial connectors called?
1, 2 and 5 look like SMB (1 and 5 are male 2 is female)

3 and 4 are SMA (3 is male 4 is female)

For your color coding I would say that they are probably manufacturer spicific. If you could post the device model and manufacturer I could get more info for you. Also the purpose for the device would be helpful.
