Is there any side effects of eating almonds daily if i have kidney stone?

No: If you have calcium, cystine, or triple-phosphate stones, no. If you have uric acid stones, also no, though you may have been advised to restrict your diet to keep purine intake low. Almonds aren't loaded with purines. You can probably ignore stuff about "acid / alkaline forming foods" from kidney-stone websites; stay hydrated and comply with the rest of your rx.
