[Interstellar] Did post-Earth humanity attempt to recover the other crewmen from the Lazarus missions?

- Hibernation allows crew to extend their lives for decades. Dr. Mann was able to sleep almost 20-30 years (10 before Cooper begins his mission, another 23 or so when they investing the Water planet), and that's assuming he was awake for the better part of a decade for his expeditions.

- The end of Interstellar shows us that the wormhole is still open - Cooper steals a shuttle to find Brandt, which would be beyond impossible if the wormhole was closed given it transported them to another galaxy. 

- Humanity is shown living in large O'Neil cylinders with manufacturing capabilities, so even if large ships for some reason could not traverse the wormhole, they could still likely build smaller ships that could. They have been on these stations for a while, Murph was approaching middle age when she made her discovery and was over 100 when she was put into hibernation for 2 years.

Tl;dr humanity has the means, motive, and opportunity

Given these capabilities and the likely hood that at least some of the mission crew are still alive, have recovery ships been sent to follow the remaining active signals and recover these astronauts?

In short, no.  Until Coop's wildly unexpected recovery something like 90 years after launch, the entire Lazarus team was considered...not quite lost..perhaps..."expended" would be a better word - which was basically part of the original mission design.  Even with the belief/hope that one would find a habitable world, no member of that team expected to see humanity again.

After his recovery, it's clear we have a space infrastructure that could support the trip but it's doubtful they'd actually commit resources to it without a clear objective - an exact location, number of survivors, time dilation factors, etc etc.  Otherwise it's just another one-way ticket.

OOU for a second, but an easy sequel would be for Coop, now substantially aged, to come back through the wormhole to beg for humanities aid in defense of the colony that Brandt setup.
