I'll try to get a start on the 5 latest requested photo identifications by Rico. I think that Player # 1 is a young Francisco Rosario.

Francisco Rosario was on the Blue Jays' spring roster in 2003. The primary photo of Rosario which I used for comparison purposes may be seen at the following link:
