What to do with improperly stored wine?

I took home a few bottles from my parents' house to help them downsize their collection since they've cut back on their wine consumption:

2017 Penfolds Bin 389

2015 Pasquale Pelissero "Bricco" Barbaresco

2020 Punset Barbera d'Alba DOC

2017 Mt Rosa Late Harvest Riesling

Unfortunately none of these wines were stored particularly well. The reds were stored in the dining room with little light protection besides being surrounded by other bottles on the rack, and little temperature control besides the home HVAC. At least they were stored on their side. The Riesling was stored in a shaded cabinet but upright, hopefully since it's under a screw top it shouldn't make much difference.

Is there any point trying to continue to age the Penfolds or the Barbaresco in my fridge when I get home? Or should I cut my losses and drink them soon?
