Gallbladder surgery and colon cancer, can you tell me more about the relationship?

None. There usually is no relation between removal of the GB and colon cancer. Given your age both colon cancer and GB cancer are unlikely. Removing your GB does not increase risk if colon cancer.
IDK any directly. Unless you have gallbladder cancer that has spread to the colon, I know of no direct relationship between having gallbladder surgery (for stones or dysfunctional gallbladder) and devloping colon cancer. Of course, having any type of cancer increases risk of other cancers - but I know of no direct link between surgery for a bad gallbladder (non-cancerous) and developing colon cancer.

What is the likelyhood of a sudden polyp in gallbladder being cancer after colon cancer in person with lynch syndrome?

Size. I know of no relation between lynch syndrome affecting the colon and the gallbladder. Gallbladder polyps are not a "sudden" condition. Small gallbladder polyps are observed & likely only represent cholesterolosis of the lining of the gallbladder. Gallbladder polyps of greater than 1 cm can be resolved with laparoscopic gallbladder surgery.
Low. Because lynch syndrome is caused by defects in dna repair, there is increased risk of cancers not only of the colon and rectum but gastric, bile ducts, prostate, etc. If a newly diagnosed polyp is found in gb, it should be removed to eliminate this possibility. See general or surgical oncologist.
Low but possible. Cancer of the gallbladder is associated with hnpcc/lynch syndrome but, overall most gallbladder polyps are benign. I would speak with your GI doctor as a cholecystectomy may be advised depending on the size and how long it's been there.

Does having gallbladder removed increase risk of colon cancer? Or does gallbladder removal cause colon cancer?

Mild link. One study showed increase in the incidence of colon cancer, not rectal cancer, in people who had gall bladder removed; however; this should not be a reason to not have your gall bladder removed if otherwise indicated due to gall bladder disease.
Gallbladder. No not at all if you need your gallbladder out then do it because the risk of gallbladder disease far far outweighs any slight theoretical risk of colon cancer.

Is there a link between removing gall bladder and colon cancer?

No. This was studied by medical research many years ago & no association was found between cholecystectomy and developing colon cancer.

I had colon cancer 5 years ago. I had to undergo 4 surgeries due to leaking after resection. No colon left except rectum. I have diarrhea 8-10 times daily. Other than the obvious inconvenience, are there any health issues to worry about?

Fiber. Fiber would help bulk up your stools. You can message me if you would like specific recommendations.
Diarrhea. If diarrhea is large volume, there is potential for dehydration and electrolyte abnormalities. Regular monitoring of electrolytes and kidney function (while the diarrhea is being addressed and treated) is recommended.
Recurrence. Congratulations! You should follow up regularly with your cancer team to make sure you do not develop any evidence of recurrence from you colon cancer. Also, talk to your oncologist about screening for other common malignancies like breast cancer, melanoma, cervical cancer, etc. Otherwise, keep trim and exercise to reduce the risk of stroke, obesity and heart disease.

Appendix, colon cancer and bdominal hernia mesh implant surgeries. Lots of scar tissue causing bowel blockages. Can anything be done about it?

Yes. Most bowel obstructions can be resolved by a surgical procedure to free up the adhesions. They can recur but it is worth trying.
Significant problem. There are no known medical treatments for adhesions. Once formed, there isn't medicine that can dissolve them. Symptomatic treatment with pain & anti-nausea meds may be helpful at controlling some of the symptoms. The main stay of treatment is surgical therapy called adhesiolysis or lysis of adhesions. Adhesions can be divided using laparoscopic techniques which may relieve your symptoms.
