If Statements help

I know how to use very basic If statements, but im stuck here :

I have a spread sheet where i record 3 outcomes, either "y" (yes) "n" (no) or "l" (late). There are 5 of these a day, I want an if statement to add all of the y's and l's together. For example if one day i had 3 y, 1 L and one N i want the cell with the if statement to show 4 (3y+1L)

Any help would be appreciated. If you need more explanation let me know, the cells with the y's and n's are B5:F5, outcome cell is G5

What I have got right now is :

=IF(B5="y",(1),IF(B5="l",(1),(0)))

But I have to do this in 5 different cells, anyway i can combine it to do it all in one?
