Answer 1

try this one this might be helpful just create a for loop to your count ,increment it ...

NSDictionary *dict=(NSDictionary *)[jsonData objectAtIndex:i];
    double la=[[dict valueForKey:@"latitude"] doubleValue];
    double lo=[[dict valueForKey:@"longitude"] doubleValue];

    NSMutableArray * latArray=[[NSMutableArray alloc]init];
    NSMutableArray * longArray=[[NSMutableArray alloc]init];

    [latArray addObject:[NSNumber numberWithDouble:la]];
    [longArray addObject:[NSNumber numberWithDouble:lo]];

    CLLocation * loca=[[CLLocation alloc]initWithLatitude:[[latArray objectAtIndex:i]doubleValue] longitude:[[longArray objectAtIndex:i]doubleValue]];
    CLLocationCoordinate2D coordi=loca.coordinate;

    GMSMarker *marker= [[GMSMarker alloc] init];
    marker=[GMSMarker markerWithPosition:coordi];
    marker.position = CLLocationCoordinate2DMake([[latArray objectAtIndex:i]doubleValue], [[longArray objectAtIndex:i]doubleValue]);
    marker.snippet = @"Hello World";
    marker.animated = YES;
    marker.map = mapView;

Answer 2

I think , You have to alloc Marker in for loop, right now you are creating only one marker,

for(int i=0;i<[jsonData count];i++)
{
  NSDictionary *dict=(NSDictionary *)[jsonData objectAtIndex:i];
double la=[dict valueForKey:@"latitude" doubleValue];
double lo=[dict valueForKey:@"longitude" doubleValue];

CLLocation * loca=[[CLLocation alloc]initWithLatitude:la longitude:lo];
CLLocationCoordinate2D coordi=loca.coordinate;

 GMSMarker *marker= [[GMSMarker alloc] init];
marker=[GMSMarker markerWithPosition:coordi];
    marker.snippet = @"Hello World";
    marker.animated = YES;
    marker.map = mapView;
.....
