The Govan club have also opened talks over a potential loan deal for Norwich and Scotland defender Russell Martin.
Cummings arrived in Glasgow on Sunday night ahead of a medical after being left out of the Nottingham Forest squad for Saturday’s defeat by Aston Villa in Aitor Karanka’s first match since replacing Mark Warburton as manager.
The 22-year-old has scored four goals in 10 starts and seven substitute appearances since leaving Hibernian for Forest in the summer.
Rangers are reported to have made a B£350,000 bid for Northern Ireland international Jones. The 23-year-old is out of contract in the summer.
Martin, 32, has not featured for Norwich since a 4-0 defeat by Millwall on August 26 and subsequently lost his place in the Scotland squad.
Rangers also made an enquiry over Hamilton midfielder Greg Docherty last week.
Murty integrated new signings Jamie Murphy and Sean Goss in his squad during a week-long training camp in Florida with Andy Halliday and Michael O’Halloran also both featuring during two victories over Brazilian opposition.
The Rangers manager told the club’s website: “Everyone who played has added something to the collective and that is what we want, we want more good players in the squad pushing and improving the people around them and challenging for places.
“If we get that training will be better, games will be better and hopefully if we react in a positive way we can push ourselves to a higher place.”
Southampton manager Mark Hughes was delighted to see his new side reach the FA Cup semi-finals but also warned that the Premier League remains a concern.
Borussia Dortmund winger Andre Schurrle was delighted with the team's hard-fought 1-0 Bundesliga victory over Hannover 96 on Sunday afternoon.
Chelsea defender Andreas Christensen has revealed that he sought advice from club legend John Terry after making a few costly mistakes recently.
