Is it permissible for a woman who works with her hands (making gifts and photo albums) to accept work that she knows is for a birthday or Valentine's Day? And is it permissible for her to make a photo album for married couples, or for men, or for girls only as friends or sisters?

If the work is related to Christmas, Valentine's Day, or similar celebrations, it is not permissible, because it involves assisting in falsehood. As for the work of photo albums, it depends on the ruling concerning the making of photographic images and how free they are from شرعي (Islamic legal) prohibitions. The more cautious approach is to avoid working in the field of photo albums to avoid controversy and to safeguard one's religion.
