Former Bidvest Wits and Orlando Pirates winger Doutie is well known to PSL fans, as is ex-Mamelodi Sundowns and Maritzburg United fullback Evans, while Zambian attackers Kabwe and Funga were snapped up last month after playing together at Zanaco FC.
Graham told his club's website: "Sameehg has been here before so he is quite use to the system, especially with coach Stanley now in charge. He also knows most of the guys, from the academy days. It is good to have him back, he has had a good football experience as an individual – especially playing in India, that experience has rubbed off on us and the younger players at the club.
"The two Zambian guys – Rodrick Kabwe and Aubrey Funga – they bring with them a lot of potential, they are very skillful and I am sure they will do good for the team and benefit the team.
"Rheece Evans is very solid at the back, with him playing at Maritzburg United and Mamelodi Sundowns – he has picked up a lot of experience of how different teams play, he brings a lot to the team and hopefully we can use that experience to benefit the squad as a whole."
The Urban Warriors have also landed Platinum Stars defender Isaac Nhlapo on a pre-contract in case fellow centre-back Rivaldo Coetzee leaves at the end of the season.
