On the top rifle, you will notice what appears to be a Winchester Model 94 Buttstock, mated to a 21st Century version of the Model 81 reciever with whaqt appears to be a Model 94 lever. For some reason, the barrel looks like it came off of the Model 81 rifle. The forend or forearm, looks like it came off of the BAR ShortTrac Rifle.
As for the 2nd rifle, the buttstock looks like it came off of a BLR '81 Lightweight rifle along with the reciever. The barrel looks to be more Winchester styling than Browning, just from the finish.
UPDATE:... Just went on the Winchesterguns website. Checked out the Model 94 Timber Scout rifle. Just as I thought. It's a Timber Scout mated to the BLR'81 rifle.
