In Japanese, "~ san （～さん）" is a title of respect added to a name. It can be used with both male and female names, and with either surnames or given names. It can also be attached to the name of occupations and titles.
As a rule of thumb, in Japanese business life, the surname name is always followed by the honorific suffix “san” (meaning “dear” or actually “honorable Mr/Ms.”). There are of course many other options such as “sama” (highly revered customer or company manager) or “sensei” (Dr. or professor).
“San” is the most convenient expression and the safest way when someone wants to show his (light) sense of respect. Using “San” expresses one's caring for others. Therefore, it is recommended to use “San” in any type of situations. “Kun(君)” is usually used for boys, especially the younger ones.
Sama (様, さま) is a more respectful version for individuals of a higher rank than oneself. Appropriate usages include divine entities, guests or customers (such as a sports venue announcer addressing members of the audience), and sometimes towards people one greatly admires.

Chan is used to add a cute friendly later to a person's name or a noun. There is no big difference from men or women using it. Although, 'chan' is used for girls and boys like Aya-chan, Yoshi-chan. But for boys there's also the use of Kun.
Calling Hideki Tanashi by his last name Tanashi means we don't need to attach the san to it. In fact, using honorifics too much in English translations can be off-putting for people. -kun is reserved for young men. You'll see female anime characters use it to refer to guys as a signal of endearment or familiarity.
Sensei, pronounced sen-say, is in its most basic sense a covers-all Japanese word for a teacher.
No, senpai is for both genders. I went to an all girls school through elementary, middle, and high school and senpai was the most used word in school.
A senpai is not necessarily someone's crush, by the way. It just happens that a lot of anime characters may have crushes on their senpai.
