Halal

It is not true to say that every locust is Halal to eat. Locusts which die in the water or on the earth are not Halal at all.  The Hadeeth from Ali Ibn Jafar, the brother of Imam Musa Ibn Jafar (AS): I asked Abul Hasan (AS) (Imam Musa Ibn Jafar): About the locusts found dead in the water or  in the desert, can it be eaten? Imam said: Do not eat it. (Wasaa'il Al-Shia, Hadeeth number 30067).

Only locusts which are taken alive then die are Halal (Hadeeth number 30068 in Wasaa'il Al-Shia).

The people in Arabia used to eat all types of locusts and many of them still eat it, but Islam forbade eating the dead locusts and the small locusts as well till it Fly.

Usually, non Arab Muslims do not eat and even do not like the idea of eating locusts, while many Arabs specially those wo live in the desert, do.

It is not necessary for the Imam (AS) himself to eat every thing which is allowed to eat or to do every thing which allowed to do. Imam (AS) is the Best and Most humble servant of Allah (SWT) and he does only the best deeds and not every deed which is allowed for general public who have their their own needs and circumstances.

Music which is used usually by the sinners is Haraam.

Yes but with conditions. It becomes Halal if you catch it or if it has been caught by a Muslim. It is not allowed to eat it if it died before catching it. Small locusts which can not fly are not allowed.

This is mentioned in many books of Shia and Sunni scholars.

It is mentioned in Saheeh Bukhari , Hadeeth number 5176 narrated from Ibn Abi Awfa. Same Hadeeth is also mentioned in Saheeh Muslim, Hadeeth number 1952.

Haraam sea food is not allowed to be eaten but it is not Najis, that is why, Halal food cooked in utensils that were used for Haraam seafood is allowed.

This is only for the non Halal seafood because it is not Najis, otherwise, every non Halal food like meat, chicken etc is Najis and utensils used in cooking it become Najis and must be made Taahir before we can use it in cooking.

It is good to mention that non Halal seafood includes every seafood except scaled fishes and prawns.

Wassalam.

Yes we can say that because the God of Prophet Ibrahim is none but Allah.

Wassalam.

Yes it is permissible to feed the animals non Halal food.

Halal rules are for human beings, not for their animals. Animal can eat any thing .

Wassalam.

Usually, supermarkets in non Muslim countries sell variety of items which are either allowed or Haraam. The money earned from selling the Haraam items is not permissible while money earned from selling Halal items is allowed. Try to know the ratio of it as much as you can.

You need to avoid using the Haram part of the money as much as you can.

If you are sure that a part or percentage of the income is from unlawful source, the situation can be :

A. If you know the percentage or quantity of the unlawful funds, then you must take that unlawful part away and give it back to its real owner or if the real owner is unknown to you then to give it as Majhool Al-Maalik (funds of unknown owner) which is given to the Marje' of Taqleed to distribute it among the poor on behalf of the real owner.

B. If you do not know the exact percentage of the unlawful money or items, but you estimate it to be less than 20%, then you must pay the Khums of the whole amount, which will make the remaining amount allowed.

Wassalam.
