Foul shot by wrong player
 

Ref give ball to player to shoot 2 shots he makes 1st before shooting 2nd they say he is wrong player wave off make and give ball to other team no 2nd shot correct???

Assuming you're talking about high school rules:

This is considered a correctable error that's been caught within the proper time frame. Wipe out the point from the first free throw. You didn't mention any fouls, but if there were, you would wipe out any fouls except those that were unsportsmanlike, intentional or flagrant. Put the correct player on the to shoot his/her two free throws and resume as normal.

wrong player shoots foul shot
 

college 2 shots caught after 1st is made

Wrong player at the line
 

Would they shoot Both Shots in College?

Yes, they should cancel out the first free throw and shoot both free throws with the correct player. This is true for all major rule sets in America.

Foul Shots
 

Thank You!!

Under FIBA rules this would've been correct. (Art. 44.3.3)
