Verb tenses

[Turkyash]

Hi! I am trying to learn English and these verb tenses are VERY confusing.

Please explain which of these choices are correct.

I wonder how many bones he (had,has) broken before achieving that skill level.

How many bones (has,had) xyz (broken,broke)?

Any explanation will be appreciated.
PS. Should it be (will, would) be appreciated?

Thanks!

I wonder how many bones he HAD broken before achieving that skill level. <-- It must be past tense because the sent4ence continues to talk about something he achieved after the broken bone but before the present.
I wonder how many bones he has broken - present tense.
I wonder how many bones he had broken - past tense.

How many bones (has,had) xyz (broken,broke)?
HAS and HAD are both acceptable depending on time (past or present)
BROKEN is the correct ending.

Any explanation will be appreciated.
PS. Should it be (will, would) be appreciated?
WILL and WOULD both work. 'Would' is perceived formally to be more polite.

Verb tenses are tools that English speakers use to express time in their language. You may find that many English tenses do not have direct translations in your language. That is not a problem.
