That's a pretty broad question and pretty far in advance relative to when colleges start looking at runners, especially males who have the tendency to develop slower.
That being said I can tell you my experiences.
When I was a freshman in hs I ran 2:01/2 for the 800, 4:45 for the 1600, 10:05(?) for the 3200, and was strong in XC. I went to a DI school on scholarship, but it needs to be noted that I also ran a 4:18 1600 and 15:11 for a 5k xc (so take it with a grain of salt) my senior year. 4:19 1600 and 9:23 for the 3200 my junior year. In essence, between freshman and senior year a lot can happen/change.
Quite frankly I wouldn't give any target times to freshman regarding college scholarship times (current goal times are way different) because at that time they mean almost nothing. There might be a slight trend among the significantly faster times going to college on scholarship but that doesn't take into account other sports/burnout/too much mileage/etc. I know guys than could run a 4:30 1600 as a sophomore only to never come close to that time again and basically fizzle out in his senior year. I also know guys who could barely break 5:10 in a 1600 or 11 flat in a 3200 only to run 4:25 and 9:14 his senior year.
Furthermore, it depends on the school as well as the level (DI,etc). Some schools focus on 800 runners, some xc guys, some look for long-term potential, some look for those who can come in and immediately score.
Basically there is no good answer. Just tell the kids to run and enjoy it and tell the parents to back off and just let things be, after all they're only 13-14 years old.
