A man is a male human. The term man is usually reserved for an adult male, with the term boy being the usual term for a male child or adolescent. However, the term man is also sometimes used to identify a male human, regardless of age, as in phrases such as "men's basketball".
Yes it is allowed for men to apply henna on hands as tattoo provided that it does not have the name of Allah or any name of The 14 Infallibles according to obligatory precaution. Henna for men should not be like what is usually used by women.
Every forbidden in Islam is damagingly harmful. We might know little of the harm, but we believe that Allah (SWT) Knows everything and He wants to protect us from its harm.
In our Shari'ah, we do not have any prohibition or censuring of marriage of a Seyid/Seyidah to a non-Seyid/Seyidah. This is a cultural practice and personal preference of a parent.
One must bear in mind though that if one is to marry a Seyid/Seyidah, they must stress on a higher level of honouring and respecting them, due to their lineage to Ahlul Bayt (a.s.).

It is not permissible to take part in inappropriate topics whether participants are males or females or mixed as far as the topic is inappropriate.
Some special topics for men only or for women only, can be appropriate if discussed among same gender only but are inappropriate if discussed in a mixed group of males and females.
Muslim must avoid any inappropriate discussion looking not only to the topic but also to the participants.
A woman is not required to marry a man just because he wants to marry her. She is also not required to give a reason for refusing. Marriage is optional.
The opposite is also true - that is, a man is not required to marry a woman just because she wants to marry him, and he is also not required to give a reason for refusing.
The idea a woman must give her life over to a man simply because he asks - unless she had a reasonable excuse - would indeed be an astonishing form of male privilege.
Main criteria for marriage in Islam is religious practice and good morals. Financial status is not among the main conditions. In fact the Prophet (SAWA) proposed a marriage between very poor person ( Jowaibir) and a very rich woman (Al-Dhalfaa').
The man should be able to earn livelihood for him and his wife and live with his wife with dignity.
Lowering the gaze has been emphasized upon in Quran very explicitly as we read the order of Allah to the Prophet (Tell the believing men to lower their gaze) Sura Al-Noor, verse 30. Same order was given for the believing women to lower their gaze (Sura Al-Noor, verse 31).
Those who remember Allah and obey His orders as obligatory order, Lowe their gaze and protect themselves from looking at sinful scenes.
We have many authentic Hadeeths in this regard which also emphasize on lowering the gaze and the punishment of those do not lower their gaze.
Muslim man must lower his gaze always and never look at females who are not wearing Hijab. Sitting with non-Hijabi women should not encourage them or give wrong message endorsing their act in neglecting the orders of Allah in Hijab.
Muslim married man is not allowed to go for Mut'ah marriage with a woman from People of Book (Christian, Joe, Magi) but after permission from his Muslim wife.
Muslim men have been ordered in Quran to lower their gaze and not look at Nin Mahram women who are not covered by proper Hijab. (Tell the believing men to lower their gaze and protect their private parts (from sinful sexual acts). That is purer for them. (Sura Noor, verse 30).
Next verse says: And tell the believing women to lower their gaze ( from looking at non Mahram men) and protect their private parts.(from sinful sexual acts).(Sura Noor, verse 31).
These orders aim preventing acts which can initiate or cause sinful sexual acts and maintaining the purity and piousness in the hearts of men and women when dealing with each other. It is a type of prevention which is better than cure. Sinful looking initiates sinful desire which can be a step towards sinful sexual act, that is why, lowering gaze has been clearly ordered in Quran and authentic Hadeeths.
Yes it is permissible for a woman to propose marriage to a suitable man. She can convey her proposal through a trusted person or through any suitable way like a letter or an email etc. Such proposal should be studied very carefully because it is not common among men, and it might be misunderstood or misused if the man is not pious enough. The man should be with high degree of faith, religious practice and manners.
Yes this is allowed.
