Osman Kakay and keeper Seny Dieng are close to agreeing new contracts with QPR.
Rangers have been keen to extend the contracts of Kakay, Dieng and Conor Masterson, while manager Mark Warburton would also like Dom Ball to be given an improved deal.
Masterson has signed three-year contract and talks with the other three players have been ongoing.
Right-back Kakay, 23, has been with Rangers since the age of eight.
Swiss stopper Dieng, 25, was signed four years ago after leaving Grasshoppers.
He impressed while on loan at Doncaster last season, having previously done well during loan spells at Dundee and Stevenage.
There is some doubt over the future of Joe Lumley given that fellow keeper Liam Kelly has three years remaining on his QPR contract and Dieng is now pushing for a first-team place.
Like Dieng, Lumley is in the final year of his contract.
Rangers are currently minded to offer Lumley a new deal but would consider any bids made for him while the transfer window is open.
Meanwhile, doubts remain over the futures of Bright Osayi-Samuel and Ryan Manning.
Their contracts expire next summer and they have so far rejected Rangers' offers of a new deal.
