How do you read the "he" with stroke underneath?

I can't see your image, but I think you might be referring to the independent pronoun for he, which is "huw" in aramaic. There are two other variants of it with an underscored letter "H". To my knowledge, this means the "H" is silent.

So you would have:

huw (maybe pronounced "who", or "who:wa")
:uw (maybe pronounced "uw", or "u:wa")
:w (possibly pronounced with a very quick "wa")
