Going to the masjid will give them knowledge about Islam provided that they respect the masjid and wear as should be.
In general most imaams will allow non-Muslims to enter the mosque provided they adhere to the rules and etiquettes set out for such occasions.
Green colour means the of Muslims and white colour means non Muslims
Yes. Even Islam-derived religions like Druze, Baha'i, and Sikhism do not celebrate Ramadan. If a person considers Ahmadis to be non-Muslims, then the answer changes to No since Ahmadis do observe Ramadan. However, there is much controversy over whether Ahmadis are or are not Muslims by different people.

It is the fourth Islam pillar (in sunni view of pillars of Islam) that a Muslim should fast the month of Ramadan (the 9th month on Islamic Calendar) unless there are licit reasons not to fast the month or part of the month. However, voluntarily Muslims are encouraged to fast Mondays and Thursdays as well as the three days of the middle of the Lunar month (called alaiyam embid).
Well, it would be hard finding the prayer times and celebrating the Eid.
This may or may not be right but in class at school it was said because if you know that a prophet fasted for a long period of time, so to remember the story Muslims fast to and gain rewards, etc. At the end of Ramadan there is Eid, a religious celebration, where you have a big banquet! Ramadan is celebrated wherever there are Muslims who wish to celebrate it.
Muslims still must respect and co-operate with non-muslims.
on hijra 2nd year Ramadan 17 The Makkan non-believers, 1000 well-armed, attacked the Muslims at Madina. The Muslims, 313 in number, almost without proper arms came out of Madina and faced the Non-believers at the field of Badar (70 miles away from Madina) on 17th Ramzan, 2 Hijra. 70 Non-believers were killed, 70 were made prisoners. 14 Muslims were martyred.
First, it is not allowed for a Muslim; or even non Muslims; to judge on God commands whther fair or not fair. Second, it is fair for Muslims; and should also for non Muslims; to be forbidden from practicing dating. Islam teachings stricts any sexual actions to be only within licit marriage.
Non Muslims don't go on Hajj.
Yes, assuming that we are talking exclusively about Muslims, but there are exceptions. The Muslim female that has her 'period' or menstruation cycle cannot fast until it's over and she has showered along with going back into the religion of Islam. The really sick doesn't need to nor does the one traveling where they might not know day from night. Non-Muslims do not have to fast during Ramadan, because it is not their tradition, but in Muslim-majority countries, they should abstain from eating in public.
A Muslim is not allowed to date around for the sake of dating but to find a life partner, if your intention is to find a wife to marry and you date her to get to know her it is fine because only Allah knows your true intentions.
