Identifying Roku Device Remotes

I have three Roku Devices in my home in different rooms

Recently we had new floors installed in the entire downstairs  and carpeting installed on the second floor. We took down all televisions and devices including three different Roku players..

Now that everything is being reconnected I cannot identify wihich Roku remote belongs to which player.Just before the dismantling I was having trouble with more recent model Roku Stream player and Roku Sound Bar; specifically with sound and pairing with the my LG smart tv. My older Roku p;layer is the ULTRA,(cant I.D. remote )

 

The ROKU sound Bar has been connected to HDMI port .The  device  is reset, starts up, the menu shows,  but I cannot connect to the wi-fi   because I cannot  access the Settings to connect ,

The light on the player is flashing yellow

 The main problem is identifying the remotes for each player.

The later model remotes have the  voice mic emblem. Which is all but one, which i found in a junk drawer, probably 2010s model.   I found a model # on one of them 9012x or 9210x,

 

any help is appreciated.  I can be more clarifying if needed,
