He is known for respecting. (is it right? ,if i don't write further,like he is known for respecting other? No, the sentence does not point out who is being respected. "He is known for respecting others, he is known for respecting women, he is known for respecting the rights of dogs."

2- Teaching of other is not easy.(what does it mean?) This could be written, "The teaching of others is not easy." "Others" are different people - not yourself.
According to me ,there are two possibilities
a-Teaching other is not easy.

b-What other teaches is not easy
Is a correct
Is b correct
Is a & b both correct depending upon condition.

Teaching other people is not easy. To teach, or instruct, someone else is complicated, it is not simple. For example, it is easy (not complicated) to turn a computer on. It is not easy (it is difficult and sometimes complicated) to write a computer program.

Teaching of others is not easy.(Is it also wrong?)

"The teaching of others is not easy" is OK, but not very natural in everyday English.
In response to your first question; you could say, "He is known to be respectful."
