How did you define those 5 objects?
Something like this?
new CrateObjects[5];
Then try this.

stock PlayerNearCrate(playerid)
{
    new Float:x, Float:y, Float:z;
    for(new i = 0; i < 5; i++)
    {
        GetObjectPos(CrateObjects[i], x, y, z);
        if(IsPlayerInRangeOfPoint(playerid, 10, x, y, z))
            return i;   
    }
    return -1;
}


CMD:loadforklift(playerid, params[])
{
    new vehicleid = GetPlayerVehicleID(playerid);
    new crate = PlayerNearCrate(playerid);
    if(GetPlayerState(playerid) != PLAYER_STATE_DRIVER) return SCM(playerid, COLOR_DARKRED, "You must be the driver.");
    if(!IsAForklift(vehicleid)) return SendClientMessage(playerid, COLOR_DARKRED,"[SERVER] {FFFFFF}You must be a driver of a forklift to load a forklift.");
    if(crate != -1)
    {
        ForkliftLoaded[vehicleid] = 1;
        DestroyObject(CrateObjects[crate]);
        ForkliftObject[vehicleid][vObject] = CreateObject(964, 0, 0.9, -0.12, 0, 0, 0);
        AttachObjectToVehicle(ForkliftObject[vehicleid][vObject], vehicleid, 0, 0.9, -0.12, 0, 0, 0);
    }
    else return SendClientMessage(playerid, COLOR_DARKRED,"[SERVER] {FFFFFF}You aren't near any crate.");
    return 1;
