Niyyat for missed fasts

Q: I have to make up for a lot of fasts I missed, as well as for some that were most likely invalid (due to issues with ghusl). Is the following intention permissible - "I intend to fast today to make up for a fast that I missed or one that was invalid".

Selling branded items and trading in shares

Q:

1. Hermes is a fashion brand and its name was taken from a Greek figure. However, the bags do not have the Greek symbol for Hermes. Is it permissible to sell the bags anyway? What I mean with Greek figure is Greek 'god' (their words, not mine).

What about selling Louis Vuitton bags or Jordan Sneakers. Their name doesn't represent a 'god'. Just a person. 

2. My second question is about day trading. First of all, is day trading stocks (non-haram businesses) permissible. And what about day trading crypto. So, trading ARK for BTC. Both are cryptocurrencies. Is this trade a form of riba because it seems like it is a 'gold for gold' trade (both cryptocurrencies, but they have different values and meanings).

3. You said that investing in halal companies is permissible, however the interest that they are involved in is totally forbidden. But does that make my earnings forbidden (and does it come in the category of 'witnessing riba')? 

Explanation of Nabi (sallallahu alaihi wasallam) going through difficulty when passing away

Q: Please explain the meanings of these Ahadith:

Hazrat Aisha narrates: “Having seen the agony the Prophet suffered while dying, I will not envy anyone’s easy death.” (Tirmidhi, Dead, 8).

In another narration, Hazrat Aisha said: “The Messenger of Allah died on my chest. Having seen it with the Messenger of Allah, I will not consider the severity of death bad for anyone.” (Nasai, Dead, 6).

Feeling lust when being touched by one's mother

Q: A few months ago after I had returned from a journey to my home, my mother touched me with her both hands on my face and she was crying as she missed me. She touched me 2-3 times and I felt strange and did my best to stop the feeling which might constitute hurmat musaharah. The feeling and notions stopped after few seconds but the private part reached its limit. This all happend within 15-20 seconds and my mother stopped touching me on my cheeks. Does hurmat take place? My parents are of liberal mindset and I'll have to face problems after announcing this. Should I keep quiet? Or reveal this to them?

Wazifa for protection

Q: Please confirm which is the proven and authentic way of sunnah for all kinds of protection because I heard that surah al fatiha X 7, Ayat al kursi X 3 and surah Ahad, surah Falaq, surah Naas X 3 times each in fajar, maghrib and before sleep is sunnah practice. 

Beating the duff in the musjid

Q: I came across this hadith: Aisha (Radiyallahu Anha) narrates that Rasulullah (Sallallaahu Alaihi Wa Sallam) said, “Proclaim the nikah. Have it done in the masjids. Beat the daffs (tambourine drums without jingling discs or bells) for the occasion.” (Tirmizi vol. 1 pg. 207 Qadeemi) So is it permissible to beat the daff in masjid?
