What are examples of Mortal and Venial sins?

Can we ask forgiveness for the sins of another person?

1 John 5:16 - 17

ESV - ¹⁶ If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life - to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that. ¹⁷ All wrongdoing is sin, but there is sin that does not lead to death.
