Pictures show these are vegetable-tanned leather chairs. The color derives from the natural tannin color of the tannin agent. These leather types unlike aniline leathers the color will darken just like our skin. The stains are evident that these are absorbent leathers and most liquid stains are penetrated. And the most effective way of moving these stains from within the leather structure is to be done with Hydrator-3.3 in the wicking process without aggressive mechanical agitation so as not to distort the smoothen of the skin.

Am I looking at 2 chairs?

Picture #1, #2 & #3
Are the reddish stains Red Wine or Blood. It would be easier to clean wine than blood stains. Blood is from protein and coagulation to the protein fibers is a bigger problem removing it than the wine stains.
The dried and crack stains must be other stains that contains alkalinity that result in cracking. It would need a neutralizing with Acidifier-2.0 to neutralize the alkalinity to a squeaky feel if tap water finger testing feels sticky or slimy prior to the cleaning processes.

Picture #4, #5 & #6
These stains is quite clearly from red wine that would require the special treatment form d’ Tannin-3.5.

Picture #7.
Shows browning on the right side. The entire panel would require a treatment of d’Tanish-1.3 to reduce the browning effect.

The recommend processes is as follows:

A] Restorative Cleaning
Use Prep-4.4 > Cleaner-3.8 > Rinse-3.0 > Hydrator-3.3.

B] Stain Removal
1] Blood – d’Protein-11.0 > d’Tarnish-1.3 > Rinse-3.0
2] Red Wine – d’Tannin-3.5 > Rinse-3.0
3] Browning Treatment – d’Tarnish-1.3 – Rinse-3.0

C] Leather Rejuvenating
1] Fatliquor-5.0

D] Non-Stick Rub Resistant Protection
1] Leather Scent-D
