All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
Nothing of what you mentioned is considered kufr; rather, it is only waswasah (obsessive whispering), and you should disregard it and not get carried away with it so as not to allow Satan to have any control over you. Waswasah is a serious disease, and indulging in it leads to confusion, pathological doubts, difficulty, and hardship. Just as the Muslim is enjoined to avoid all acts of kufr and sins, he is also enjoined to avoid waswasah and accusing himself of kufr every time that he does something doubtful.
Allaah knows best.
