I wanted to see if my answers were correct because I'm not sure if they are. If they aren't, would someone mind explain to me why?

I believe number 4 is - resolveré

the sentence as you have it says : any problem will help you
Because : -ayudará- means -help- in future term

On the other hand, if you put resolveré it will say : I will solve any problem...
because -resolveré- means -solve- in future term

The number 1: is -ayudaré- for the same reason.
I punt an -e- at the end of the words because I’m putting them in the term of first person.

Hope this helps ✨good luck
