Use loop for that.

Код:
new Float:min = 9999.9;
new minindex;
new Float:distance;
new Float:px, Float:py, Float:pz;
GetPlayerPos(playerid, px, py, pz);
// pointx/y/z[] is an array, that contains all the points you want to get the nearest from
for(new i = 0; i < sizeof(pointx); i ++)
{
    distance = PointToPoint(px, py, pz, pointx[i], pointy[i], pointz[i]);
    //Change this to your function to get the distance
    if(distance < min)
    {
        minindex = i;
        min = distance;
    }
}
