The League Two outfit also fielded three teenagers from the French island of Reunion.
Uldric Samaria, Remy Lauret and Hamada Noussoura Adifan were recommended by Didier Agathe, who was a former team-mate of Imps boss Chris Sutton.
Midfielder Adifan caught the eye against Staines and Sutton told BBC Lincolnshire: "Ady is very young, he is raw but he has good potential.
"Physically he certainly looks up for it we just need to work hard with him. We have two or three more weeks with him then we will make a decision. We will give them a fair crack of the whip and they will get other opportunities."
Former Exeter winger James Berry, who was given a chance to impress in the game, is unlikely to be retained.
