Caramonraistlin's suggestions are correct for the WW2 IJN
Asagumo (an Asashio-class destroyer, I think) but if your kit has the hull number DDK115 then it is the post-war JMSDF destroyer. (I have Nichimo's kit of its sister ship,
Minegumo). Your other two kits are also JMSDF ships, of a different class.
Unfortunately I don't know much about JMSDF paint colours! I don't think any model paint suppliers make exact matches for their colours; I believe WEM's Colourcoats range originally included them, but they were discontinued due to lack of sales. My suggestion would be to do a web search for some colour photos and then find a paint which is the closest match.
Here's a photo of
Takatsuki. The colour appears to be a medium-to-light neutral grey, darker than USN Haze Gray.
