Father

It is very wrong to pray for your own father's death even if he is a very bad person. The supplication against parents  can have very bad effect on you.

You must treat him nicely and pray for his Hidayah ( guidance). and forgiveness.

Wassalam.

Child does not belong to the father only but belongs to both father and mother. Father is fully responsible for all livelihood expenses of the child and the mother, while mother is not responsible to spend on the child even if she is rich.

The Prophet Muhammad has ordered every one to look after his mother, his mother, his mother, then his father.

In the unfortunate situation of separation between father and mother, mother has the right of custody during the childhood years ( 2 years for boy and 7 years for girl) then custody will be for the father.

Wassalam.

If you are sure that you visiting such relatives will definitely make
you fall in to sinful acts like shaking hands with the opposite gender
or eating or drinking Haraam food, then you should not visit them

If such sinful acts are not there but the female members who are
not wearing Hijab will come in front of you, you can avoid looking at them by lowering your gaze.

Wassalaam.

It is against the teachings of the Prophet (SAWA) and Ahlul Bayt (AS) to create a condition in marriage which was never put by Islam. Caste condition is simply un-Islamic .

Delaying the marriage of a female who needs marriage, for no real Islamic valid reason is a sinful act.

The Infallible Imams were from Bani Hashim yet they got married to pious ladies out of Bani Hashim and even out of their language and culture. There is no question of caste in marriage in the teachings of Ahlul Bayt (AS).

The authetic Prophetic Hadeeth says very clearly : If marriage proposal comes to you from a person whom you accept his faith and manners, you should accept it, otherwise the earth will be corrupted with Dispute and wide spread evil.

إذا جاءكم ٬من ترضون دينه وخلقه فزوجوه ، إن لا تفعلوه تكن فتنة في الأرض وفساد كبير.

Wassalam.

Prophet Yaqoub (AS) and all the prophets are Infallible. He was victimized by some of his sons who felt jealous about their bother Yousuf and they did what they did which caused Yousuf and his father Yaqoub lot of pain for long time.

There are many points mentioned in books of Tafseer of Quran about Yaqoub which can guide fathers how to deal with their children.

I will try to take time to brief some of these points in the future Insha Allah.

Wassalam.

She is still virgin and needs consent of her father or paternal grandfather for marriage.

Wassalam.

Muslim is not allowed to attend or take part in any non Muslim religious ceremony.

The child mentioned in your question is a Muslim because of his Muslim father. Islam says that any child who is born from Muslim father or Muslim mother, is a Muslim.

الولد يتبع أشرف الأبوين 

There is no question of baptism ceremony for a Muslim child.

Wassalam.

Yes, your marriage is valid.

Your  stepfather has no say in your marriage. If you were virgin (first marriage) you needed permission of your  biological father if he has not removed himself from your life.

Even after marriage, if your biological father who looks after you agrees, the marriage is valid. In any way, according to what you have written, your marriage is valid.

Wassalam.
