As salam alkium insha’Allah this will help you
I personally have never heard about spending less time with the rich not sure why this is a thing since some of the companions of our beloved prophet SAW was rich also we know some prophets were rich but it may just be a tips so that you dont envy this world or get attached to it I’m not sure Allah knows best
I’m not quite sure what you mean by trabel? If you’re talking about traveling.... It was narrated from Ibn ‘Umar (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “If people knew what I know about being alone, no rider would travel at night by himself.” Narrated by al-Bukhaari (2998). There are also some other few Hadith stating that it is highly adviced not to... but if this was meant for only back then you know with the deserts I don’t know Allah knows best
As for the 3rd: It is not haram (forbidden) in Islam to accept charity that is freely given from a Muslim who is trying to please Allah. It is forbidden to beg when a genuine need does not exist. No Muslim of faith would ever beg on the streets, in the malls or by the doors of cars for sustenance. In fact, Muslims are instructed to avoid giving charity to one who begs regularly.
It is forbidden for a Muslim to tell friends and neighbors about loss of employment and home with hopes of charity. It is with sincere hope though, that Muslims will indeed help those in dire need and that charity be given daily, weekly and monthly to please Allah, the "Creator, the Benefactor and the Forgiver of Sins, not just at Ramadan. Insha’Allah those answer you’re questions
